You are standing in a field at 5 a.m. watching a giant silk envelope fill with fire while the rest of the world sleeps. Private rides are better because you aren't bumping elbows with six strangers while you are trying to take in the view. These pilots book up months in advance for calm weekend sunrises, so we need to plan the money before the calendar fills up.
A $900 flight is a big hit to a checking account if you pay it all at once. We can use the Discover it® Cash Back to break that cost into $60 monthly payments. This works because of the 0% intro APR for 15 months on purchases and balance transfers, which is a set window where the bank does not charge you for carrying a balance.
If you still owe money on the card after those 15 months, the standard interest rate kicks in on whatever balance is left. This is not free money; it is a timed loan that gets very expensive the moment you miss the deadline.
