HI darren,
Your quite right. Thomson told me originally 8 weeks, then 6 weeks, then 4 and yesterday when I phoned them it went back up to 6 weeks!
I phoned them up again this morning to be told to phone back on 2nd July, but this afternoon I was looking through this site and a couple of posts read that seats were now loaded for July/August, hense I managed to get the exact seat numbers I wanted. Had I listened to the advise given to me by Thomson call centre, I probably wouldn't have got the seats I was after.
Thanks again to this site - it's come up trumphs!!
Pat
