When Alaska uses Sky west which it does on many flights in and out of PDX, The planes use " Gates" that are outside of the terminal and are a long walk to and from the planes. Also you must board and deplane using a ramp. I have difficulty walking so going into Portland was difficult. Going out was worse . We walked to nearly the emd of this "Tunnel " only to be told there was a problem with the plane so we had to take the long walk back to to the terminal and then back out again when the plane was fixed. I will look for a Southwest flight next time I go to Portland

First time traveling with them and they were great leaving on time arriving on time very clean planes 😊

Great! No issues at all. Friendly staff, on time flight, and smooth, comfortable flight.

The airline itself was extremely comfortable and the staff were wonderful. The communication was excellent amongst the pilots and flight attendants and the passengers. I was throughly impressed by the cleaning crew that came on the plane immediately to ready it for the next flight. I have flown a bunch of times post Covid pandemic and have never seen this! I gave the “okay” rating for the food and entertainment because I didn’t order food and there wasn’t entertainment offered through the plane (only your personal devices).

The flight both ways was pleasant and uneventful. The staff was friendly, accommodating, and overall very helpful.

Offer snacks/meals for people with food sensitivities. HAVE TV SCREENS!

The one stewardess was rude about helping me put my bag in overhead….she said “ Is it heavy ?” (I am 73 yrs old)

That flight was a terrible experience. Flying to Portland was not much better. I will not ever fly Alaska Airlines again. I have a temporary disability due to recent neurocervical surgery. I cannot lift heavy things, I cannot walk long distances without vertigo and fainting, and I required wheelchair assistance. I showed up an hour and a half before my flight. The wheelchair queue assistance person was rude and chastised me for showing up so late. An older couple showed up almost an half an hour AFTER me, and she was sweet as pie to them. There was a long wait for wheelchair assistance as they were backed up. When I got to the gate, the gate attendants were rude and again, I got chastised for being late, even though it was not my fault they were backed up. When I asked for help with my bags and boarding the plane, they told me it was my fault and they were not obligated to help me. I was treated like a big inconvenience because I had a wheelchair and I couldn't "just walk." One of them literally rolled her eyes at me. I kept silent, because I just wanted to get home and I felt like they would not let me on if I complained, but I was practically crying. When I got down to the door to board, the wheelchair person left, and I asked the flight attendants for help. They said, well, you'll have to stand there and wait, even though I said I couldn't stand very long, and another passenger said, "Oh just let me do it" and helped me down. I tried not to bother the inflight attendants, because everytime you did, they acted exasperated and stressed out. I paid $7.50 for a bag of Pirate Booty and a tiny turkey beef stick for dinner. I needed wifi to work during the flight, and it kept crashing on me repeatedly and resetting my online work, costing me valuable time. I had to pay twice to get it on my laptop and phone, but I did get a refund when I returned. When I got to NY, the Portland agents had not arranged for a wheelchair to meet me and I had to stand for fifteen minutes waiting for the very nice young man who found an empty chair and had to wheel me and another passenger with carry on luggage to the front of JFK all by himself. Never, ever again. You all should be ashamed of how you treat people with disabilities. The other people who needed assistance to get on this flight did not fare much better than me, from what I could see.

My experience for a sort flight was perfect and hassle free.

I didn’t like not knowing my seat till I got to the airport - and my boarding group was F (last).

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

Lost luggage again. Our second trip to Mykonos, and 2nd time no luggage.

Terrible. I didn’t fly and I had an important meeting the next day.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

Nice aircraft. Plane was PACKED full and distance between seats was tight. Had it been more than a two hour flight it would not have been tolerable. I had much more knee space on the JetBlue flight I went out on.

New ridiculous policy by american destroyed my allegiance to american. As a million miler with american, I expected it would be easy to get on an earlier flight when I got to airport earlier than expected, and save a five hour layover. WRONG. The online app would not let me switch flights, So I called, and was promised a call back in 90 minutes. HAH! The customer service desk at DCA said “we no longer have access to changing a flight on our screens. If the app couldn’t do it, I should send a letter to American, but there’s nothing else possible!”

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

It was right on time and crew were very courteous

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

8 hr delay. had to buy another ticket with another airline

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

I appreciated the upgrade to free cary-on bag and seat selection at no charge

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

9 hours of delay!! Was not able to check my luggage that I paid for!!!

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.
