Thomson Airways 767's long haul seat config

Evening everyone,

Just after some info and I am sure with the large amount of knowledge on here someone can help.

Flying out on a P&O Caribbean cruise later this year, Manchester to Barbados did this last year and flew there with Thomas Cook on one of their A330s. Now I know they have increased their economy pitch to 33” but were stuck in the isle and my seat neighbour was a tad big and I was squashed for 9 hours.

With this being a P&O charted flight it was on a first come seat basis.
This year they have introduced a small charge to allow you to choose 12 weeks before travel(just outside at the moment so cannot book), we are flying with Thomson Airways B767.

Now had a look around and a tad confused, do they still have a certain number of their own 767’s in what they call long haul config if so is it still 2x4x2 I know it’s 33” but was wondering if they have took one seat from the middle to make 2x3x2, also the chances are that it could be an x First Choice 767 which are 2x3x2 in the back.

Hope you can help as I would love a tad bit of space this time.

Rgds
