The programme is due to start in in a few days for the A320 Family fleet and in 1Q17 for the A330ceo fleet. All the cabin modifications will be completed by the end of 2017
Weird that they went for the Thompson Vantage (also used on DL/LX/SN/OS) instead of the Recaro CL6710 they are currently fitting on the A330neos
That means they will have two A330 aircraft with Sogerma Solstys seats, 7 A330 with Thompson Vantage, 9 A330 with Recaro CL 6510, and 14 A330neo with Recaro CL 6710.
