As a current TCX pilot, I have to say there are worse places to be. T&C's are good. Maybe not the best, but certainly far from the worst. Generally most guys are good to fly with. We still have a few old die-hards who seem to find it difficult to move on post MYT/TCX merger but they are in a minority.
If you are recruited to the airbus, then previous posters are correct that 330 is only available at MAN/LGW. If you do not have a 330 rating, then placement onto the 330 is on an as needed basis. Airbus F/O's are not automatically rated on the 330. Also bear in mind that LH is not the crown jewel it used to be. Bean counters don't want us lazing on beaches for days on end!
Time to command is certainly not short. There are minimal upgrades (if any) in the pipeline and whilst we do have a retirement bulge coming up, there will be c300 F/O's in front of you!
In terms of SFO rank, as long as you have 1500hrs and an unfrozen ATPL, you should be placed onto this payscale. That supposes that the company has nothing else planned. Most new joiners have had a couple of seasons as summer only prior to being given a permanent position.
Good luck to those that apply!
