There are the usual modest frequency changes on long established routes. Particularly of note, and probably a sign of market dynamics, is that Manchester decreases by 14 flights a week, Glasgow decreases by 8 flights a week, and Aberdeen and Newcastle each decrease by 7 flights a week. Inverness however increases to 16 flights a week.
Helsinki also decreases to a daily service.
Larnaca increases to 2 to 3 times daily from Friday 12 July.
Pisa increases to 18 flights a week and also transfers from Terminal 5 to 3.
