.... By the time you join the only 737 bases will be Newcastle, Luton and Belfast. Over the summer Liverpool, Glasgow and Edinburgh will be changing 737s for A319s.
If you join without an ATPL (ie frozen), it is not a problem but you will only be eligibe for the lower pay bands of F1 and F2 rather than those for SF1 & SF2. As soon as you have the hours and do an LPC (standard sim check) you will be upgraded to the higher salary, be called 'Senior First Officer and get a 3rd stripe on your uniform!
The tax rates quoted apply to any of the UK 737 bases.
Hope that helps.
