The seats are not comfortable if you are not tall.

The flight was cancelled and I was re-routed via an inconvenient routing proposed.

Overall great! They could add more entertainment option. They kept running out of vegetarian food options and I got travel packs. This happened on all legs of the flight. Need to plan for it better - I am sure you have some data analytics from all your travels.

Better service to offer drinks in the middle of the trip

They can improve Everything, a 12 hour flight has just 2 meals and the meals are 7 hours apart, wtf are they thinking. At the very least they should have 2 refreshments like some small snacks with some water or some other refreshments since there are people travelling with medical conditions. The services and seats were genuinely horrible

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

We boarded late, sat on the plane for 45 minutes, I was sweating on the plane and there was a child that screamed and kicked my seat almost the entire flight. The parent nor the crew would do anything about it. Food was very good.

I always have issues to connect with BA WIFI. Nothing to blame BA for but there is always an issue getting a gate at any London Airport whether the flight is on time or delayed. But overall a great flight.

LUGGAGE ISSUE - Upon luggage drop off the 4 staff were sharing only one functional POS machine. The contactless transaction asked for PIN, which I provided. In my app it showed 2 transactions automatically: 1 contactless denied and 1 approved after the pin input. However, no receipt came out of the POS. The lady at the baggage drop had me standing by the counter for 10 minutes to wait for the transaction to show up in their system. Which it didn't. So then we proceeded to make another payment using the chip and this time it gave a receipt. Needless to say, now I have to wait for another 7 days before I can claim the first payment back, as I was charged twice. NO ENTERTAINMENT OR FOOD ON THE SHORTER FLIGHT, just the longer one. Meaning - the plane had no screens, and the "food" was a small packet of pretzels. OVERALL GOOD STAFF on both planes.

I realize it almost has to happen, but giving up one carry-on is difficult. With the standard one in the overhead and one under the seat, I believe it could have worked. We chose British Airways because of its baggage allowance, but giving up on carry-on is a major negative in choosing BA in the future. Again, it is understandable. Everything else is top notch. Thank you.
