The worst thing was baggage claim. In my return flight I was waiting 90 minutes for my baggage. and when I asked the airport they said it’s the airline. So frustrating after an 8-hour flight.

The worst thing was baggage claim. In my return flight I was waiting 90 minutes for my baggage. and when I asked the airport they said it’s the airline. So frustrating after an 8-hour flight.

Business class seats aren't comfortable. Food was not good.

Didn't make announcements during boarding, flight attendant seemed annoyed when I asked for water. Too many hours between flights. Confusing check in at the Lisbon airport.

Chaotic boarding with no announcements. Carry on luggage needs to be checked. Bare minimum zero frill flights. Not a whole lot of anything positive to be said .

It poured rain, our luggage was sitting out in it uncovered on the transport cart while our plane was delayed! Nice business class plane for short flight to Lisbon, but more delay & rain in Lisbon, with terrible Business class seat with no entertainment & cold food on longer flight to London…ALL LUGGAGE AND CLOTHES INSIDE THEM WERE SOAKED THROUGH!!! Could only try with hair dryer to get some drying before quick turn round to train trip.

Delayed at the beginning and the end and almost missed our connection

Menzies group staff not very sympathetic good at breaking up families during the boarding process

The crew was great. There was a big guy sitting next to me who was hanging over my side of the armrest the entire time. Maybe some information about "Be considerate of your neighbors, this is tight space, be kind". The breakfast sandwich was not appealing at all.

Kayak let me choose these flights on TAP but then after 2 months, cancelled my flights because they didn't think 90 minutes was enough time for the connection. I notice that neither flight was actually cancelled. Just my reservation. Why let me go through all of that effort to find the right flights for us, only to cancel it from underneath us 2 months later leaving us scrambling to find an alternative?

It was a good experience overall. We were however delayed by over 3 hours due to a security issue with one of the passengers inadvertently leaving a power bank in a luggage she was using as carrying on but then had to be moved int check in due to spacing issues. The airline staff had requested that she checked her bags in, but should have reminded her about removing all hazardous material like her power bank. When she eventually remembered as we were on the plane, we had to turn back and go through security all over again. Hence delaying our takeoff. The incident could have been prevented if staff reminded these passengers to remove their power banks.

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Guide passenger if fhey board from front or back door cause it was a total mess

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

Nothing unexpected considering it is a Ryanair flight. It does the job. Nothing above, at all.

Take off was great but landing is always with a bump.

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

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

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.

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.
