Airline reviews

I don't understand why passengers are frequently told that they must check their carry-on luggage due to the full flight and we board and find there are multiple empty overhead cabins with space for our carry-on. Crew should be more accurate in their assessment of the space (they have radios and I assumed they were in communication with a crew member on the plan who could tell them that the spaces were full or that there were remaining spaces). We were told in no uncertain terms that any remaining passengers yet to board had to check their carry on because no space remained on the plane, but there were multiple spaces available (including some that were completely empty) when we boarded. As someone who travels with things I must have with me, I do not appreciate this misinformation which causes me delay because I have to wait at baggage claim to get my small carry-on.

If Alaska Air is going to partner with other airlines, then it has to make the transition to the connecting flight better, especially if Alaska Air is the one that is running late. When I realized our 30 minutes of lateness due to weather was going to make getting to my connecting flight home more difficult ,I would have expected more from the crew than blank stares and "sorry". My son and I had 20 minutes to get from Gate E to the end of Gate K in the Chicago airport. My 50+ year-old body had to sprint and yell to get through the throngs and have any chance of arriving to the gate on time. In addition, the seats I had chosen when I purchased the connecting flight were changed so that my son and I placed in the last rows next to the bathrooms and were separated. There needs to be better communication between the airlines if one is going to be late. The thought of not making it home on time (we still had an 1.5 hour drive to get there) was stressful and unnecessary.

It was fine. The flight was about 45-60 mins late boarding and taking off which made us miss some plans in the morning and bags took forever to get to us but that’s Logan’s fault

On time. Seats were comfortable. Staff was great. The plane was freezing cold! (And I prefer it to be cold, but it was freezing!) And they only offered water or juice. But overall, would fly again!

They had all the passengers running around the airport as they kept changing the gate (from B7 to C1 to B16). Then they were saying the flight would be delayed and then they immediately boarded it, almost standing passengers who'd wandered off thinking it was delayed.

The employee handling boarding of the plane had such a strong accent that I don't think anyone could understand a word she said. Other than that, everything was fine. The seats in coach class are too narrow (even for a small person like me), and it would really help to have pillows available on an overnight flight.

Good and easy. Seats are a bit crammed and plane was small.

Be prepared for departure delays at SFO while the runways are under construction. No fault of the airlines, so be flexible. Alaska is my favorite air line but needs to pay flight attendants for all the time they're at work, not just when in the air.

Crew was great snacks could be approved upon. Healthier options

Whoever the lady was who helped me check my bags in at the kiosk was amazing. She had red hair and was maybe 5'2" or so. I never got her name, but she was an infinity sign on a scale of 1-10.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

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

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.

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!

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The boarding was horrible. You couldn’t hear the announcements at all. Probably because there is so much in the area for businesses. They need a louder PA system. Other than that it was a good Delta experience.

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

Confusing. Delay updates were out of whack At one point it said my flight was 25 hours. Three gate changes and two delays only to change back to original departure time. Gate announcer and on board flight attendant (Alejandro) making the announcements was impossible to understand due to accent and speed of speech. After beverage service the rear flight attendants sat back there on their phones. No refills no checking in, one sweep through for trash collection. Very impersonal. Bring back Coke products

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Delayed by almost an hour - I also noticed that all JetBlue flights departing from PBI were delayed yet the weather was perfect.

I loved the wifi, much better than Delta. Seats were old. and bathrooms dingy.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Delayed 4 hours because of maintenance issue they knew about all day. Get another plane. Time is precious!

I liked that boarding and take off were timely despite a 15 minute delay due to weather. The pilot communicated with us the entire flight keeping us informed re: turbulance and slight delays on the runway after we landed.

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

United is today and old, the planes, the staff, the business processes. Yet they expect premium prices for a less than average flight experience. I should have remembered to stay away from them and will remember to stay away from them in the future since I'm traveling a lot again. In a nutshell, they suck eggs.

The entertainment wasn’t playing in the app or online.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

On time take off…US cabins look tired and need of refresh!

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

Excellent. Attendants served preflight drinks and were courteous and nice.

It was great! It’s been awhile since I’ve flown American but this most recent experience reminded me how much I enjoy flying American. Organized. Informative. Efficient. Friendly. Can’t ask for much more, except my luggage got dinged up a bit. But that could have been the airport.

It was the worst experience ever. Cabin temperature cold, for which they did not have any blankets upon my asking. We paid $125 extra for each passenger to get extra space sits; the sits were ridiculously small, tight, and uncomfortable! The flight attendant dropped ice on me and my sister! All in all, American Airlines deserves below zero!

The flight was delayed two hours, with no information as to why. The gate also changed several times which was aggravating. Would not fly through DFW again.

The inability to be flexible when you need to change a Basic Economy flight, when your company demands you book through a third party, causes raw feelings about the whole experience. A major airline should realize business and personal plans change all the time. I must save my company money on travel. Even if you have to charge me for the change, I get it. But being so rigid with a policy is not the best customer service.

The plane was freezing cold. Normally I’m fine on planes but I needed to toss a sweatshirt on this time.

WiFi was down so no entertainment and I could not work either. The flight was Very turbulent at the end (the last 20 min felt like an eternity) I appreciated the pilot for getting us there safely. The flight attending in first class was kind and attentive to everyone.

The gate crew did try to help, however they lacked the information as to whether the flight will operate or not. Being delayed 6 hours and in a limbo on whether the flight will operate or not is not fun. The airline having staffing issues is not encouraging at all.

From check-in staff to in-flight staff, everyone was wonderfully kind

The A321(?) model of the flight for 5+hrs has no seat back screens. Getting the american airlines wifi experience to watch movies on your own devices is not the same.
