For those worried about transaction fees on credit cards it is really a non issue that amounts to peanuts. The transaction fee on credit cards is around 30 cents per swipe plus the percentage.
If a student has 30 swipes for $1500 each that is a grand total of $9.00 in transactions fees on $45,000 in flight school training.
Total non issue except if you are one of the schools that wants to scam.
