Hello Robini,
First of all I will tell you that My Travel Airways does not exist anymore - it has changed its name (08May2008) to THOMAS COOK AIRLINES SCANDINAVIA.
Check the following link and you will get to their website, where you will see that the max. takeoff weight of their A330 aircraft is 230 T.
Airbus 330-300 - Thomas Cook Airlines Scandinavia
If you check the following link from AIRBUS.COM you will see that you may buy the A330 with 230 or 233 T as max. takeoff weight - obviously some airlines require the extra 3 T.

I hope that these answers are satisfactory
