Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

The person at the checkin was very helpful. We couldn’t check in through the keyosk, but the agent was very helpful.

Great price for really nice seats and the plane and staff were great, only 5-10 minute delays!

Tap was very frustrating in Lisbon. Not enough direction and help. Mixed messages of where we needed to go. Seats were not very comfortable.

Everything went as expected. Luggage arrived at my same destination and nothing disturbed my vacation.

This flight arrived late. We joined well over a thousand of other people waiting to go through customs. Air Portugal has lost my bag. We had to chase down a representative even though we had waited at the baggage claim for well over 1 hour and 35 minutes for baggage to come. No representative was there to explain the delay or to give any direction. After 1 hour and 35 minutes at least four passengers had no baggage to pick up or had a fraction of their baggage. The representative was a young woman who clearly did not have the experience to deal with what was happening. Very disappointing as of course we were dealing with great amount of jet lag and having been up for 24 hours at that point and not being able to have any of the things necessary at home that were contained in the bag was quite upsetting. That instant occurred last night at approximately 11:15 p.m. and as of 12:30 p.m. the next day I have not heard anything from Air Portugal.

Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.

Very rude person at the boarding desk; flight attendant coughing 3 inches from my face three times- not even covering her mouth; boarding process very unacceptable for older people with stairs to all planes (are you all stuck in the 1960’s?). I am sure that I am not remembering all of the negative things, but I am sure you get the message!

Flight was fine. Second meal ( fish sandwich on hard roll) was awful. My suitcase didn’t make the flight. It had been located, but won’t be delivered until tomorrow. Five days after flight

Boarding experience was awful. TAP claims I did not have check in luggage with tickets. I went 3-4 check in agents until I finally found a helpful kind agent who checked in my luggage with no fees. On top of that our flight was over 2 hours delayed with barely an apology or explanation.

The airport temperature at the airport and on the flight was too warm

It would have been better if I was not ill so I didn't go and I didn't come back and I could not transfer my tickets to a later date as Ryanair stop flying from Manchester at the end of October till next year

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.
