Foghorn,
It's been a while since any significant numbers did a paid for jet type rating to 'improve their chances.'
The memory of the vast majority using this particular forum doesn't extend that far back so I promise this isn't a knocking exercise.
Use you skill and judgement to determine the reponse of an interviewer at a turboprop/regional jet/freight company when they see a 737 in your licence.
The buy your jet rating tactic blew up in a lot of faces but it is always something a normal person will try to forget and therefore this is the last place you will hear of such personal disasters. People will only write about it here when it worked for someone they heard about. Heads remain firmly in the sand regarding all whose chances of that first job suffered terribly.
The PFO letter is just about guaranteed when there is a chance of a really good first time job and they see that shiny jet rating in your licence.
I got a wage this month and apart from a few bob on the car owe nothing to anyone but if you write me and the other working pros off when we tell you the truth it really is on your own heads. It's very difficult to attract contributions here from experienced, working professional pilots because they see exactly the same attitudes that ruined or hindered people's career when they were starting out.
This is a huge pity as the majority of you end up only getting information from those who are trying to sell you something or are only a couple of steps further up the ladder than you. The second type is actually far more dangerous than the sales person - they have to justify the decisions and outlay they made. Telling you they porked it up takes a very strong person.
That's why we run the PPRuNe seminars - nothing to sell you and we are experts in telling you the stuff ups we and our friends made over the years
