Hi Gaz,
I've just checked Thomson's website, and I know for a fact that when I booked back in March their seats with extra space specified that they were for adults only due to being situated either by the bulkhead or exit. I contacted Thomson who clarified this, and obviously makes sense as I wouldn't think that children would be able to sit in Exit Seats??
However, info on their site at the moment reads:
Extra Legroom ..
Enjoy up to a 34£ seat pitch
Suitable for adults and children
Includes access to select your seat service
£70 per adult £70 per child
Seats with extra space ...
Enjoy a little more legroom on board
Maybe next to an exit or by the bulkhead
Adult £60 Child £60
No mention of access to your seat service in the latter but it is include as we have booked and received confirmation of our seat number ... seats 15A & B which are exit seats.
Regards,
Pat
