Delta Fares

How far in advance of travel can I do my flight's online check-in? (delta)?

1. Online check-in opens 24 hours prior to departure.
2. You can check-in as far advance as 24 hours online. Although most people do it just a few hours before they leave for the airport just in case something happens while that day in advance they do it a few hours prior to. SO I would suggest maybe like 5-8 hours before you leave for the airport would be wise.
