Airline reviews

Flight delayed a bit. Boarding by seat row number in two parts. Flight attendants weren’t greeting boarders, they were talking to each other. In the outward journey much the same yesterday and that was a different crew to a different airport. I do get the feeling on Blue Island Flights that they have no interest in even allowing passengers to use the toilet . The flights are short but in fact they keep the seatbelt sign on for the duration.

Basic economy flight, random seating unless you pay extra, no refreshments, friendly and attentive crew, slightly late boarding and taking off. 40 minutes max all in

As someone who has limited mobility it was appreciated that the staff took particular care to ensure that my needs were catered for with priority boarding and assistance both on and off the plane.

Cons: "Delayed for 2 hours due to “fleet issues”, no food or water on board due to “weight restrictions”"
Pros: "Nothink I didn’t have one"
Cons: "Flybe change the flight 1hour earlier and didn’t tell me so I missed it"
Pros: "Crew friendly and efficient! Seats reason I changed from departing from Birmingham to Bristol larger more comfortable seats on blue islands flights rather than flybee!"
Cons: "Not really sure if anything !"
