For someone currently on the list, I have had a fantastic time over the last 7yrs. Done most things from short haul to long haul, small base to big base, winter contract in Canada and the Hajj.
The problem is though at TOM it is just just a job with Little light at the end of the tunnel. Yes you will get your LHS but there are just so many other interesting things out there between now and probably 15yrs minimum.
I would recommend it if your happy and settled in the UK.
Good luck to all.
