Air Luxor flew the A333 CS-TMT, i was onboard. There are also pics and Videos of LK at TMS using the A333. But agree in General the A320 CS-TMW and other such as CS-TQA/B was operating.

STP Airways is using the B767 since a while now. TP could use the 332 but they are short on 332 and their isn't reason to do so, since weight limitations wouldn't allow a full deployment. Years ago they used A313 for LIS-TMS-SID-LIS so they could profit more of the loads. Maybe if ACC requires an A332 they may be used to TMS as a triangle.

Relating C seats, agree first step is a full flat seat configuration, TP is going to be one of the last again in Europe to have an up to date product.... I saw pics of the planned new flat seats for the A350, but this will still take a while.
