Hi - Please do not waste your hard earned cash on embarking on a pay to fly scheme it is the cancer of the industry. Flying a 737 is not glamerous and it's not even fun.... ok i am ex mil and am biased cause i did fun flying but i also enjoyed my GA flying and gliding was just fantastic but i also flew 737's and i found it so shiiiiiiiiiiiiiiiiiiiiiiiiiiiiite that I stopped flying altogether and chose another profession this was after flying for 25 years.
Please do yourself a favour and use the money for something else.
If you do go ahead and do a pay to fly you will regret it.
