Efficiency was great - on-time takeoff and landing. Baggage arrived at destination (there's always slow baggage handling in Boston.) TAP food is spartan - bring your own. But the efficiency of the airline more than makes up for the mediocre cuisine.

Efficiency was great - on-time takeoff and landing. Baggage arrived at destination (there's always slow baggage handling in Boston.) TAP food is spartan - bring your own. But the efficiency of the airline more than makes up for the mediocre cuisine.

On-time flight. Nothing out of the ordinary. The food offering upfront could be better.

Delayed takeoff was inconvenient. We should have boardrd later. Coffee/ beverage service on a 7:30 flight would have been good.

Flight from Lisbon to Barcelona was ok. Business flight Boston to Lisbon was awful. Attendants should pay more attention to Business Passengers and not be so stingy with water. Worse Business Flight I have ever taken. Food was awful. Cramped for space.

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

Disastrous boarding. Entered air bridge only to descend stairs and enter a bus. Plane had insufficient storage, was old and chair recline was damaged. Air stewardess was sullen.

I wish to bring to your attention an incident involving a flight attendant that occurred on my recent journey. The attendant displayed a lack of courtesy, which was concerning. For instance, after accidentally spilling water on a passenger, the attendant dismissed the situation rather than offering a proper apology. Additionally, when I handed over my trash, the attendant reacted negatively because I placed a paper cup on the tray, she told me this doesn't go here and threw it back on my table. It was apparent that she was experiencing a challenging day, which unfortunately impacted the service provided to myself and other passengers. While I understand that everyone can have an off day, it is essential for customer-facing staff to seek support to manage personal stress without it affecting their professional responsibilities.

The flight crew was good, the flight itself was quick and comfortable

Boarding was late by 30 min due to a bus missing to take us to the plane... And then the flight was delayed by about 90 minutes, in a 60 min flight

Very agressive with bags both arrival and departures found minor damage to my luggage including my check bag being broken into nothing of value was in there so I do not believe anything was taken but definitely broken zipper into the outer pockets of suitcase

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

BA charged me 70 euros for one bag on my return after having recognized my frequent flier status and charging me nothing for the same bag on the outbound. Their employees are not well trained and rules are inconsistently applied.

I couldn’t select my seat until I checked in at the airport. Extremely difficult to talk to a customer service representative. Also, the gate announcement doesn’t appear until less than an hour before boarding.

They over sold the flight and I was not able to board. Had to buy two tickets so I would not miss my connection.

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

On the flight from Venice to London even it’s short, 2 hours 20 minutes and mostly people are on vacation, it’s ridiculous to change money for the cup of tea or coffee. Also it’s to much to charge 80$ for 1 piece of luggage

Flying economy is like being packed into a sardine can.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

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.
