0lane 2qs on tim3. Very bad food. No free wifi, only for texts. Entertainment poor and hard to access.

At boarding, the locations where we had to have our passports checked prior to boarding were very unclear. Occasional staff wandered around telling people, but in busy area of the terminal this was not obvious. It was also located well after the check in desk in terms of walking to the gate. The Premium Economy service was attentive and warm. The only big draw back was lack of restrooms, and no division or even curtain between PE and Economy.

We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

Everything was fairly easy just hard when you get to Heathrow not know your Gate number until an hour before but otherwise really everything great. Did not get my texts in time though to do me any good but that is why I still like everything the old fashioned way and print everything out.

My experience was wonderful. The professionalism of the crew was exemplary 🙂. The meals were wholesome and tasty. I have no complaints

Everything was smooth and great. I didnt like that they talk so much on the interphone during the flight.

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.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Big queues on arrival at airport despite having already checked in and only needed to drop bags off. Flight delayed which impacted on connecting flight.

The update about flights and the terminal changes information was great.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

Although business class, the seating was really cramped. The food was so so.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.
