Umm, sorry to intrude here with a reality check BUT,
You are between 33 and 39 and leaving the military.
You are likely married with kids or potentially so.
You probably don't live currently near Heathrow or Gatwick nor have any desire.
You would quite like a Captains wage.
You have a couple of thousand hours experience.
So WHY THE FLIP don't you apply to easyJet? You'd have a command course after two sims (12 months). Basic Captains pay is 74K plus 11K Sector pay plus 9% pension + loyalty bonus after 2 years.
Based in the regions though sadly no bases in RAF York Vale or East Anglia other than Newcastle or Stansted...
Home every night.
No Seniority.
No longhaul-wife-divorce-syndrome.
We have Cadets at the age of 24 leaving to join BA and Virgin last year that will be vastly senior to you...
Airline flying is boring. There are only 3 considerations:
Base,
Money,
Lifestyle.
Choose wisely.
