(CNN) -- As Hurricane Alex spins toward northeastern Mexico and southern Texas, airlines are rolling out policy waivers for travelers likely to be affected by the storm.
Continental Airlines, which has a hub in Houston, Texas, is waiving ticket change fees for passengers traveling to, from or through airports likely to be impacted.
For some airports in Texas and Mexico, the loosened rules apply to original travel dates between June 29 and July 5. If rescheduled travel starts by July 19, fare differences also will be waived. Fare differences may apply for travel starting after that date.
Passengers with original travel dates between June 26 and July 1 for certain airports in Mexico, Belize and Honduras also will be eligible for a free change of travel dates if rescheduled travel starts by July 15.
Delta Air Lines' operations in McAllen, Texas, and Monterrey, Mexico, may be affected. The airline is allowing passengers traveling to, from or through those destinations a free one-time change for travel scheduled between June 29 and July 2. Rescheduled travel must start no later than July 4.
American Airlines offers similar waivers to affected travelers with its hurricane protection policy.
