Chech "jetonly" site. On this site tui airlines sells their empty seats, and you can check the fares.
greetz!

I hope you will have the chance to visit the "flight deck" (they don't use the word cocpit in this company) BUT the policy of the company is to fly with a closed re-inforced flight deck door during the whole flight!!!

PS; TUI also uses the word "commander" and not captain, just for info

Good Luck ...
