Palmair celebrates 50 years of holidays from Bournemouth
For the past five decades Palmair has been doing what it does best – offering great holidays from Bournemouth Airport with award winning service and taking care of you from start to finish. This year – our fiftieth flying from Bournemouth - will be no different."
I believe Palmair as the holiday arm of Bath Travel have been operating for 50 years while Palmair as an airline (albeit using Flightline and then European aircraft) have been around for 15 years.
