There isn't much more you can pack into a summer programme for the current charter operators unless you give up low profit Spanish routes and go for more Turkey flights. That will happen next year. The Spanish routes will be available for the exremely short haul 319's and the Turkish routes with no Spanish /French ATC shennanigans will be taken on by longer range aircraft.
Resurfacing 07/25 will put a spanner in the works though, 7 tonnes short on 17 and 5-6 tonnes short on 35 for DLM/AYT and LCA.
