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.

They gave away my business class seat. No explanation and no apology. Told me I had to take the downgrade if I wanted to get to India. Then no WiFi for 10 hours. Just ridiculous. We should not work with this company at Deloitte. They don’t know how to run a business.

The British airways from Dallas to London is not great , the food is not good at all but BA from London to Delhi is amazing food is great.

It made me feel safe that the crew diligently check our seatbelts. One crew member was so very patient with a passenger in explaining to him why his daughter’s car seat had to be buckled in a certain way. This passenger and his wife were quite argumentative and she maintained her composure brilliantly.

Missing 3 out of 10 checked in bags.Transfers in London and Chicago are chaotic.
