Logan changed the schedule so I couldn’t use the hotel rooms we’d booked which were non refundable. £250 down the pan!!

Everything was fantastic. My trip was short and sweet. No problems. Just remember. My paid checked in was i belive 2 to 3 lbs overweight. I believe I could have been given a discretionary pass rather than paying or unpacking. Especially as flight was probably half full only. Thank you

I really enjoyed the good hot tea and biscuits. I loved the tartan plaid head-rests on each seat and the fact that there were all different. The crew’s uniforms are very sharp looking, too.

I booked this flight thru Kayak and then had to cancel within 24 hours of booking. They only refunded part of the fare, saying that was the usual practice. I was not pleased.

Everything! Not sure if there's really anything that could make it any better

Very quick trip from Southampton to Edinburgh Arrival a long way from baggage and up 3flights of stairs no lifts or escalators
