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.

Business lounge in Naples is very spartan with poor food and not very comfortable. Late departure from gate, ride bust then wait on runway for 30 minutes. Almost an hour late departing. Business class was middle seat empty. We exit row do reasonable comfort. Service was friendly and prompt but drink offerings limited with some selections requiring extra charge.

Liked that my American Airlines status seamlessly transferred to BA so luggage check was free. Flights were on time, boarding quick. Wish they didn’t assign connecting gate so late at Heathrow.

The entire process was flawless and as expected flying first class. The only thing that I have a complaint on...when first boarding, the plane was EXTREMELY cold; then when we were trying to sleep, it was way too hot - just better regulating (especially trying to sleep) would have made it perfect.

Food was not good. Tasted stale and dry. When seats moved to lie flat they were very uncomfortable. No free internet. No live tv. Not flight map. Arrived safely and on time. Boarding easy.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working. - Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!
