It was my experience w Kayak that was negative. I’m never using kayak again

The Business Class seating arrangement hasn't been upgraded yet. When getting up to go to the bathroom, you have to climb over someone's stretched out legs.

Terrible three cancelled flights due to weather then unable to make rebooked flight next morning with Veuling due to travel restrictions when I called to complain I was put on hold for 90 minutes then hung up on. No one at airport willing to help. Never again

The service was wonderful. Heads above the flight out on American. I love British Airways

I liked the pilot he was super positive. The seating on this A320 was ridiculous I have never had so little space fora four hour flight. Really was ridiculous. The service was also very poor and attituded. Not what I expect from BA a real disappointment.

Crew was super lazy. Trash languished for hours and hours. 20D where my wife was, the screen was not touch pad and after 2 compaints to flight attendent, he finally showed us the wired control. My screen, 20E would not fully stow, just stuck up a little but inconvernient. My seat control was extremely difficult to engage. My foot rest would not. Flight could not land and circled for over 15 minutes. Since the connection was tight and our boarding pass did not show which terminal, we missed our direct flight to Austin and had to be rescheduled through DC which added 5 hours to our flying time. Bags were checked to Austin but did not arrive same day. Finally received them 24 hours after we arrived but only because I was extremely persuasive, Agent in London was very helpful in reschuling flight.

I washed attendant for assistance and she never got back to me. I asked her a second time and she said she would check. She never did. The flight was over an hour late taking off No food service was offered despite over 4 hours on the flight

better seats (very uncomfortable), access to wifi was a nightmare, and food was blah.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).
