The food selection has been better in the past but due to Covid it is understandable. This particular flight did not have any entertainment and the Air Canada App did not work to access movies.
Reviews
My luggage got delayed, trying to reach out the airline and no updates for me where my luggage is and when it will be delivered to me.
Reviews
Kayak cancelled my return flight without notifying me. Fortunately, British Airways got me on the same flight with modified connections.

Poor communication from boarding staff, airport staff not a clue. Communication on board was un decipherable and airline lost baggage.

Flight attendant for first class is definitely not a morning person. Oh and the WiFi DID NOT WORK!
Reviews
Boarding at BCN was the worst experience ever
