Are flights busy at 6AM? The probability for a delay is at its lowest (20% or below) from 6am – 11am. Early morning flights have less runway traffic, planes ready to take off from the night before, and fewer planes already in the air. Days of the week can impact the ticket price, along with delays.

Depending on the airline, travelers may be charged a rebooking fee to get on another flight. Some airlines may also charge the difference in airfare — meaning a missed flight can be a costly inconvenience.
The TSA and airports want you to get there earlier, each for its own reasons. The agency does not like to be rushed with screenings, even if there's a long security line. Airports want you to take advantage of their incredible shopping and dining facilities, which you can't do if you're rushing to the gate.
