Possibly there is a misunderstanding here about what might be expected for the quoted £20k?
Without wishing to enter any debate about the rights and wrongs of paying for a Type Rating or Line Training...
A typical 737 TR will consist of about 10-14 four hour sessions in the simulator, including Licence Skills Test. This, along with relevant technical groundschool might cost around £15k.
To gain the TR on the licence, a 'Base Check' or 1 hour of circuits is flown on an actual aircraft, costing possibly a further £5k. So to have the TR on one's licence might well cost around £20k, giving just 1 hour of flying the actual aircraft.
If 10 sectors of 'line training' are offered, believe me, these are very unlikely to be included in the £20k for the TR, and might well be charged out at a further £20k, as suggested. As line training is specific to an airline's SOPs, whilst valuable experience, they are not particularly useful to any future employer.
So you are not getting 10 flights for £20k, rather you might well expect to pay £40k to get to that position. So that is nearer to paying £3,600 per ACTUAL flight! Oh, and I hope I don't need to remind you that this sum is on top of the major fortune you will already have paid to train through the PPL, hour building, ATPL exams, CPL, multi, IR and MCC before even considering the privilege of paying for the TR and 'line training'.
In explaining this carefully, I simply wanted to give a degree of perspective and reality to axelpilot2008's hope that he would:
"get a good few hours in the actual [737] aircraft itself" for £20k.
