The people who are likely to take an interest in Jet2's type rated sponsorship scheme for the LHS are those coming out of the RAF. They will take direct entry captains with suitable command experience (ie Tristar, Nimrod, etc) directly from the RAF and to a pilot leaving the forces £53k looks like a reasonable salary. The alternative would be a job with a "higher level" operator in the RHS with perhaps a long wait to command.
However, I have to agree with the previous post that there are better alternatives out there and until the penny drops with Jet2 that they will not be able to crew their aircraft on uncompetative terms they will continue to struggle.
Nevertheless, I wish the company well with their operations from Manchester.
