PHOENIX - Tropical Storm Isaac has already made a mess out of air travel for some.
South Florida airports were returning to normal operations Monday morning but airlines are already warning of cancelations in and around New Orleans as Tropical Storm Isaac nears.
Airlines canceled more than 230 flights on Monday, according to flight-tracking service FlightAware . The vast majority of cancelations stemmed from the storm, which is expected to grow to a Category 1 hurricane and hit land late Tuesday night.
So far travelers at Phoenix Sky Harbor International Airport have not experienced flight delays or cancelations due to Isaac.
However, major airlines warn fliers to expect them over the next few days, especially at Gulf Coast airports.
Many major US airlines offer some sort of flexible re-booking policy for those affected by Isaac. They advise fliers to check the status of their flight before heading to the airport.
Meanwhile, some fliers traveling out of Phoenix Sky Harbor will be able to get through security a lot quicker starting Tuesday.
There's a new trusted traveler program available at Terminal 4. It allows some travelers to skip screening steps, like taking off shoes, removing laptops and filling plastic bags with liquids.
To take part, folks need to be frequent fliers on selected airlines, pay a fee, and undergo background checks.
