I reckon that Jet 2 have added 13 additional weekly departures commencing from today (or 39 x weekly extra return services between today and the end of the month) Unless I have missed something it looks like 2 extra departures each day apart from Wednesday, when there is only 1.
Monarch were timetabled to have 533 departures during the month of October, of which I think 19 operated (on Sunday 1st October, should have been 20, but the night Ibiza was cancelled)
