Tap air portugal first has you pay for the flight. Then you realize that seats are extra. Had i known that i would have booked emirates instead for a few dollars more

Dreadful - queued to get onto a bus, stood for 10 minutes on the bus, drove to the plane, stood for another 25 minutes on the bus outside the plane. When allowed on we could only board from the front & were seated in the furthest row back. The second bus was allowed to board from the back so chaos ensued!. The flight was an hour late - nobody said why, nobody apologised. On arrival at Heathrow we stood for nearly 30 minutes before being allowed off - again with no explanation,

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

the crew was very friendly. The check in staff was a different story. I was flying club and when I arrived at the check in desk the two people behind the desk waved me to another person. They were too busy chatting. This person checked me in and said to walk to the gate immediately. At it was 1h12mins before the flight, I asked if I could use the lounge. No, he said. Straight to the gate. Obviously it was crowded, uncomfortable and irritating as the flight was delayed and a herd of people were standing in front of the gate, hoping to get in first

Flight canceled two hours beforehand, BA reticketed us so that we would have had to leave from Edinburgh instead of Glasgow, where we were already at the airport. We would have arrived in Boston too late to get home to Vermont. Instead with some pressure we were reticketed from Glasgow on Lufthansa, which avoided Heathrow, a great benefit after our horrible experience at Heathrow when we arrived in Britain three weeks earlier. (Kayak assebled an itierary that did not leave adeqate time for the connection at Heathrow, where thousands of people were trying tio get through inadequate and badly staffed security and staff did not know the slightest details about where and which lines we should get in.) The British Airways travel experience is not to be recommended these days.

One of the flight was cancelled. My experience was poor.

THe flight, crew and service was good. The only problem was the long delay and that the Captain's announcment about the delay was only in English on a BUDapest Hungary flight.: And no one spoke Hungarian from the flight crew.

Horrible check in process. The app was unusable and the website very confusing

The food could have been better, but that is secondary. I felt safe.

Check in was unnecessarily slow. Not enough agents and the 3 there were working in so- mo. Terrible.

The seats were comfortable and dinner was good.? I ended up with food poisoning, not their fault. I caught it somewhere in Barcelona. I didn't tell the flight attendant so it was up to me. It is a good airline. I was just ready to be home

Very bed boarding, there was overbooked and make a lot of problems and noises

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.
