From the article linked above.
The top ten most popular routes this summer are:
Palma de Mallorca with Vueling, TUI and Thomas Cook
Malaga with Vueling, Ryanair and TUI
Amsterdam with KLM
Doha with Qatar Airways
Edinburgh with Flybe
Alicante with TUI and Vueling
Dublin with Flybe
Dalaman with Thomas Cook and TUI
Tenerife with Thomas Cook, TUI and Ryanair
Paris with Flybe
Hopefully that means Doha is around the 9000 to 10000 mark for June
