Its expensive but, the "LOI" thing is what kind of gives me some "hope".
Surprising, you are willing to drop almost $102,000 USD, equal to almost 55 lacs just on
"some hope".......
Do you know how many flying schools have run away with peoples money.
BTW, it does not cost $72,000 USD to get a commercial in USA; you can easily do it in $40k to $50k with multi & CFI... For that much money, you can have your ATPL with hundreds of hrs on a multi engine & go to any corporate or cargo operator.
Good Luck is all I can say...... Hope things do turn out as you guys HOPE
