Airline reviews

Sadly the experience with the airline is worse one ever. Starting from the state of the inside that was filthy that flies was flying around our legs. The food is expensive than a restaurant, imagine a family of 4 spending almost £50 for just sandwich of bread and ham no tomatoes and lettuce in it and a small container of crips that is not up to 20 pieces and a can of coke or Pepsi, and unfortunately that is a person ffour hours pay of work before tax. I know the blame will go to high cost of living but even at that the price is too much.

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Notified as to why there’s a delay with our flight.

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

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

Would be better if there is phone charging ports available

We arrived at the airport by taxi so as to be there two hours ahead of take-off. On arrival I received a message stating that the flight would be 85 minutes later than planned. An hour later another message stated that it would be a further 20 minutes late. There was no mention of the almost 2 hour delay once we boarded. Needless to say, they didn’t trumpet their “arrive-on-time” signal. At least we got there eventually.

Long delay. Terrible airport - too busy, not enough seating or food/drink outlets.

Cardiff is a great airport but they pen you in at a gate way too small for passenger numbers. Called to the gate too soon and air conditioning was not in operation despite the heat. Cardiff should do better as a small relatively quiet regional airport.
