Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

I was put into business class. Wow! My flight attendant was great! The food amazing’

The gate at London Gatwick had confusing signs for the different zones and the staff seemed harried because people didn't know when it was their turn to come to the desk. Plus, with there were too many carry-on bag travelers, myself included. The charge scheme for checking bags is frustrating. If you travel light, you want the freedom to leave as soon as you deplane. When you are forced to gate-check your bag simply because the flight is fully booked, you lose whatever time you'd hoped to save because you're still stuck waiting for your bag to come off the conveyor belt.

Not so good with their baggage handling as they damaged one of my check in luggage

All went well on the flight, not happy of course with having to pay for a seat and in hold luggage of £50

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

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.

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.

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