Delta Air Lines and AirTran Airways encouraged travelers whose flights may be affected by Hurricane Gustav to check their flight status, and the carriers are waiving certain fees for those who change plans.

Atlanta-based Delta said those whose flights are canceled or significantly delayed can get a refund. The airline is waiving certain change fees for those traveling to, from or through Fort Walton Beach, Pensacola and Panama City, Fla.; Gulfport, Miss.; Louisiana; and Mobile through Wednesday who want to change plans with a new travel start date by Sept. 8.

Delta also is waiving certain change fees for travel to, from or through the Dominican Republic, Grand Cayman and Jamaica through Monday. However, passengers must pay for any increase in fare.

AirTran, which is based in Orlando and has its main hub in Atlanta, is waiving certain change fees and fare adjustments for passengers with flights booked to or from Gulfport, New Orleans and Pensacola through Monday who change their plans to another date within seven days of the original travel date.
