Bulgaria Air should stop using buses for boarding if possible. It is very inconvenient and delays the departure

Easy check in. Hot snack with wine if desired. Then chocolate, tea or coffee. Altogether excellent.

Seats are quite small, but due to the plane being empty we were aloud to switch seats to have more room

The water was handed out as we were entering the plane, instead of when we are set down and our hands are free of luggage. There was absolutely no food offered from Sofia to London, except a low quality chocolate, which was not delicious. The flight between London and Miami was ok, as far as service and food, but it was absolutely freezing, throughout the whole aircraft, especially in the back seats, I had to cover my head with a scarf, besides using the blanket and still I was feeling extremely uncomfortable. The passengers seating around me shared the same opinion. We did ask for something to be done about it. The gentleman did try to adjust it, but the effect last very short time, and towards the end of the flight it was extremely cold and blowing strong again ….

Cons: "Staff seemed confused and would not let us seat at our assigned seats which we picked in order to accommodate our baby. Instead they put us in an even worse spot and decided to ignore the people that took out seats and left them be."
Cons: "Them actually refunding my flight when I couldn't legally travel due to COVID lockdowns."

Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

Horrible flight. First delay in boarding of approximately 30 minutes. While in the plane, the flight attendants huddle and we get an announcement that the crew's legal time was exceeded, that they don't have replacement crew and that they will need to cancel the flight. One would think that they would know that their time was to be exceeded BEFORE boarding. Took for ever to deplane. Then we were told that flight would not be cancelled but gave us a departure time of 21.15, which of course was not fulfilled. Arrived in Valencia, luggage took 30 minutes to arrive. Absolutely unacceptable

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

At the boarding gate, passengers were offered the option of checking in their carry-on luggage, as the plane was full. However, they failed to specify that they would not be dropping it off at the exit. Instead, everyone had to wait over 30 minutes at the airport carousel, and to everyone's surprise, not even the carry-on luggage, but the checked luggage, was the first to arrive. An hour later, we finally collected our bags. Lesson learned: I will never check my carry-on luggage with Swiss Air / Helvetic Airways again.

Not good. We returned on united airlines and the food was horrible.

The cabin was warm and few used the blankets. I should’ve upgraded.

The plan was delayed for takeoff by an hour, but we ended up making the landing on time which was a nice surprise.

The crew was very friendly and nice! Very smooth flight.

The meal was wonderful and strawberry ice cream was a plus.

Absolutely amazing! Best airline i have flown with, huge difference to United!
