Construction is scheduled to begin Monday on new terminals at Dallas' Love Field airport.
The changes are part of a $519 million overhaul of the airport that is expected to be completed in 2014.
Until completion, travelers are going to be forced to deal with the construction that will use temporary terminals while the old ones are torn down and new 20-gate terminal is erected.
Crews are starting on the Continental and Delta terminals first before moving over to Southwest's terminals.
Travelers using the airport should park in Garage B for Continental or Delta flights and Garage A to reach Southwest's gates.
The airport, and its 6 million passengers, bring in about $2 billion annually to the city of Dallas.
The overhaul is being paid for by the airport and Southwest Airlines.
