Congratulations
Just to expand on Pilot Pete's contribution ...
I joined thomsonfly on the 737 at MAN through CTC.
If that is where you are joining us from, for the first 6 months, your salary will be paid by CTC at 1000/mth, after the 6 months, you will move on to the standard S/O salary scale.
During those first 6 months, you sill still get full duty pay and sector pay.
