I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Food was terrible Not many options Stewards dont care Delay

The ride was good but no food ot entertainment hence, it was just over an hour flight.

they made me check my carryon. There was space in the overhead bins.

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

I bought internet for the flight. Don’t waste your money. I wasn’t able to download a 1 Mb file from Google Docs during a 3-4 hr period. You can only use WhatsApp and email if you are willing to wait.

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Short flight so not much to rate. Surprised I had to pay for a soda.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Very good need to offer better choice of food for business

Boarding and crew was great. Flight was cold, need layers. Deplaning was hard. We had to take stairs off the plane and I was separated from my travel companion because we were not seated together and they would not let him wait for me to get off so we were forced onto different shuttles.

Check in and boarding was easy, crew was cheerful. Not much to read or do on the plane and our neighboring passengers were talking loudly so we could not sleep. But overall good. Great coffee.

Flyplay is the only way I travel to Europe. Had a 15 hr layover in Iceland. Normally this would suck, but I regret a car and saw the black sand beaches, several waterfalls and sky lagoon. And finished with lamb at cafe Loki.

did not get the seats we had specially paid for

This is a no frills airline. You cant expect much for the price. Low cost flight, clean, nice staff. That's all I need for the price. If you want more, book with another airline and pay more. For Europe trips, PLAY is the ONLY airline I use

Misleading instructions for check in. Although I did virtual check in and was instructed to head to security, once I was at security, they told me to go back to Play ticket counter and get paper tickets. Also, beware that Play doesn’t participate in TSA PreCheck. I didn’t know that, despite entering PreCheck info when I purchased the tickets. I wasted time in the TSA PreCheck line as well. So we had two setbacks at check in.

It's a budget airline, so forewarned is forearmed. Yes, you pay for everything like carry-on, checked baggage, seat selection, but that's becoming the case with major airlines. Bringing your own snacks and entertainment on board is highly recommended. It's no frills, but the crew, the plane and the flight itself was great. If you want pampering go for a larger airline. If you just want to get from A to B in comfort and safety, Play is a great choice.

It is a low cost airline. Staff are courteous. There is no entertainment. Food is purchased.

Upon boarding, the people at the gate were extremely rude, there were no outlets on a 6 hour international flight, there was no entertainment, all food and drink was purchase only (even snacks), and my seat reclining function was fully broken. The only redeeming quality was the flight attendants were extremely nice. This was by far the worst flight I have ever been on in my entire life

I don’t know how international flights can’t have media screens to keep people entertained for the long flight. Ugh.

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

The flight was provided by Aer Lingus and our seats were in a poor condition (15A & 15C). They looked like they needed repairing/replacing and were uncomfortable for such a long flight. Also the arm rests on Aer Lingus planes do not lift more than around 45 degrees, instead of the usual 90 degrees upright, meaning you cannot maximum the space between you & your travel companion so as to be more comfortable for such a long flight.

Very bed boarding, there was overbooked and make a lot of problems and noises

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5

It was very good. We got a late start by about an hour and a half. However I worked rather have that than crash. It was purely mechanical. They had our tickets ready when we came off the plane in London for the next leg. The only mishap was when we got to Lisbon my husbands luggage made or bit mine didn't. All was not lost because I did finally get it 2 days later. I was really pleased that they c made the effort.
