I will be flying either either delta or jetblue and have flown them with them many times. Delta has this policy where you can cancel up to 24 hours even if your flight is less than 7 days away. I know jetblue requires your flight to be at least 7 days apart in order if you want to cancel it.


If i were book a ticket at say 9pm central time on jetblue site, what time exactly till i have tomorrow to cancel free of charge? Is it 24 hours? Or is it a few hours more than that because of the midnight?


Now if i were to book a flight after midnight say 1am central time, I can only cancel till 12am meaning 24 hours? Or does booking a flight after midnight means i have almost 48 hours? Such that you book it September 3 at say 1am.
You can cancel up till September 4 at 12am or September 5 at 12am?
