Understanding the Delta Airlines Check In Policy

Check-in closes at different times depending on how you're checking in:

Online / App - Closes 60 minutes before domestic departure; 60–90 min for international.

Airport Kiosk - Closes 30 minutes before domestic; varies for international routes.

Counter Check-In - Closes 45 minutes before domestic; 60 min for international departures.

Bag Drop - Available after online check-in; must meet standard cut-off times.

Pro Tip - Missing the check-in deadline even by a few minutes may result in the cancellation of your reservation without a refund. Always aim to check in at least 90 minutes before any domestic flight and 2–3 hours before international travel.
