I would have liked an opportunity to move to a different seat ( even would have checked in my hand luggage)as I had health issues where I didn't have to clamber over the passenger next to me to for toilet use/ movement [ She was a highly unpleasant neighbor to sit next to]. In addition, I found that my European phone plan had run out of data and so I was not receiving emails from yourselves on airport wifi to be able to check in online and verifications difficult as did not accept the ticket number I had. I asked for an extra blanket but was told there was none. Then I saw other passengers receiving them. I couldn't eat the food and asked for snacks : Stewardess said " on the way" but they did not bring. The best bit was the check in process in Lisbon. Very efficient. However, I did not understand why we had to collect our bags at Washington then go through customs again. It was not explained. I also with my leg and health issue had approximately mile walk to the gate ( which then changed) . There appeared to be no moving walkways or help provided.

Boarded plane and then delayed 1.5 hours while on the plane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

We were given vouchers we couldn’t use with a 5.5 hour delay

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

They removed our booking without telling us. Cost us thousands to book last minute

The decided to just remove our booking without telling us. It ended up costing us thousands

We never made it onto this flight due to BA's lackluster organisation.

The international flight from PHL to Lisbon was one of the worst I’ve experienced, ever. What was really disappointing was the entire experience of comfort and service in the coach cabin after takeoff. The food was inedible and the wine served with dinner was such low quality - it tasted of petrol. I couldn’t eat more than a bite or two of the chicken entree, being worried it would make me ill. The service took so long to reach the entire coach cabin, I ended up having the lights turned off on me as though I had to rush though dinner (though as I mentioned, it wasn’t as if I ate much - only the salad). Most of the attendants seemed generally annoyed and were not friendly or polite. While there was some turbulence, it wasn’t too uncomfortable and I know that is just a chance. The temperature of the cabin was so warm, even a friend a row or two up and on the other side of the plane felt like this. To top it all off, the seat was so uncomfortable and flattened/overused, I had back pains for DAYS afterward.

The air hostess were good, cheerful, but I didn't like the boarding. My son and I initially bought our flight tickets, making sure it included 1 luggage and a carry on. Tickets were purchased for British airlines, but we were merged with American Airlines. At checking in our languages, we were told, we don't have luggage prepaid so we had to pay extra $125 each and almost £60 on our way back. I think that's unfair.

I never got the flight. Someone hacked your information and sold me a fake flight. Didn't know this till I tried to check in and was told the flight didn't exsist and it was a fraudulent ticket. I'm not sure how to get this fixed but I had to pay $1500 to book a last minute flight. I understand that this was not Kayak company that sold me a fake flight but I was sold a fake flight based on my booking with Kayak. I ended up having to pay for an extra night hotel stay. I guess I need to start by contacting someone at kayak to get this resolved. My bank has stopped all bank transactions because of it.

Economy seats are so small and compacted so close together that comfort is negatively affected, especially on long flights. However that is due to aircraft design, not anything the airline can do about it.

Every flight was delayed. They lost our luggage for days.

3/4 bags delayed and 1/4 damaged at the other end. Flight was freezing

The crew were good. The flight was on time. The entertainment choice was ok. But the food was bad, tasted and texture were awful.
