Travelers passing through San Francisco International Airport (SFO) won't have to worry about the airport's runway closure for too much longer — the airport is finishing up construction a week early.

The airport expects the runway to reopen at 9 p.m. Thursday, a week ahead of schedule. SFO is still warning travelers to expect flight delays and potential cancellations until the reopening, and that they should reach out to their respective airlines for updates.

The runway has been closed since Sept. 7 and was expected to reopen Sept. 27. The construction has led to many flight delays and cancellations.

United Airlines is letting customers change their flights or connect to different cities via a travel waiver as a result of the runway closure. The airline also warned passengers on its website that it had reduced flights from its schedule ahead of time and rebooked customers accordingly. Customers will be able to change flights to one 24 hours before or after their original flight.

"We have already adjusted our flight schedule at SFO during the runway closure, and customers who are impacted have been proactively notified," American Airlines spokesman Curtis Blessing told USA TODAY. "Per our normal schedule change process, if a change doesn’t meet a customer’s needs, they can make additional changes and/or seek a full refund without fees."

Alaska Airlines has a warning for travelers to expect SFO delays on its website and says it has rescheduled certain flights, though it does not mention a specific travel waiver.

Southwest Airlines also has reduced frequency and retimed flights in accordance with the SFO reduced capacity. Southwest has not issued a travel waiver but does not charge change fees
