I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

I have noticed that the airlines, including this flight, pretend there is going to be turbulence, announce such, and say they can’t do beverage service. There is no turbulence and the seat belt light goes off 10 minutes before they ask for tray tables up and seat belts back on. They are just trying to spend less money and it’s quite transparent

I enjoyed the flight. I did find it strange that when I arrived at my seat although I had paid for a window seat that I was assigned a middle seat. Thankfully I was between a couple and they wanted to sit together. Please do a better job with this BA!

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

The lack of organization at the boarding gate was shocking. It was impossible to determine where the line was and it was hard to understand the announcements. It was so confusing that my wife wanted to get on the wrong flight. I am also annoyed that BA is adopting the sleazy policies that the budget airlines invented of charging extra for even the first checked bag or choosing your seat.

My flight was cancelled and I was rebooked onto 2 flights on American Airlines: one from Heathrow to Charlotte and then one from Charlotte to Tampa.

My flight out of Miami was delayed by 2 hours which meant I had to quickly make other arrangements for pick-up in Glasgow. A $9 voucher for food was issued. That’s not much of a gesture in my opinion.

We were never contacted that our flight from Glasgow to London was delayed. Got to airport six hours early to find that we were going to miss our connecting flight to BWI. Our flight is scheduled for two days later and they only gave us a voucher for one night hotel. E we’re delayed on the front end too and had to fly to Edinburgh instead of Glasgow arriving six hours and taking a $200 cab!

The crew were very friendly and helpful. Also, the airline was very strict and not very helpful when I wanted to start by boarding from Heathrow airport instead of Glasgow international airport. I stayed 10 hours in the airport and no hotel or any form of compensation was provided. That sucks.

Flight canceled two hours beforehand, BA reticketed us so that we would have had to leave from Edinburgh instead of Glasgow, where we were already at the airport. We would have arrived in Boston too late to get home to Vermont. Instead with some pressure we were reticketed from Glasgow on Lufthansa, which avoided Heathrow, a great benefit after our horrible experience at Heathrow when we arrived in Britain three weeks earlier. (Kayak assebled an itierary that did not leave adeqate time for the connection at Heathrow, where thousands of people were trying tio get through inadequate and badly staffed security and staff did not know the slightest details about where and which lines we should get in.) The British Airways travel experience is not to be recommended these days.
