Whippersnapper, they don't call me Sir!!!!
Ryanair Pilot, the time to command at many of the UK charter airlines is looking very long at the moment, and if you were to choose them then you will be joining as an FO on around £38-40k to start. British Mediterranean I think are expanding at the moment so possibly an earlier command with them.
The charters do vary, we are undercrewed this summer (although not if you talk to the management) and are generally working 90-100 hours per month, with some single days off, 7 day runs, early starts after days off and plenty of night flights. Winters can be quieter, but not necessarily that quiet - flying 90 hours in a "winter" month isn't that uncommon, although its not every month.
Just a thought.
