Alaska Airlines, which flies more than a fifth of its flights to Hawaii, said today it is changing its minimum check-in time prior to departure for customers traveling on most domestic flights to 40 minutes, from 30 minutes, regardless if a bag is checked or not. The minimum check-in time for international flights remains at 60 minutes.

The policy change is being made so that travelers on Alaska Airlines can expect the same minimum check-in time at almost all airports the carrier serves. The exceptions will be at airports where the check-in cutoff is already 45 minutes, such as Atlanta; Denver; Las Vegas; Newark, N.J.; and Philadelphia. Passengers traveling from Guadalajara, Mexico, have a 90-minute check-in cutoff time.
