I have flown Monarch back in day of the 757 and A300 many times between Manchester and Alicante. Always booked through AVRO. They were just the usual charter airline and never thought anything great or outstanding about them. Nowadays, I would never consider booking a flight with them. Think times have changed and better deals can be had and I find jet2 holidays hard to beat. I think that's their problem. People see them as old and expensive and to a certain extent legacy. Just my opinion.
