Washington (CNN) -- Two airlines say passengers who won't be able to attend President Obama's speech tonight can fly home early without paying change fees.
The last night of the Democratic National Convention, including the president's speech, was scheduled to be outside in Charlotte's Bank of America Stadium. However, severe weather forecasts prompted organizers to move it inside to the much smaller Time Warner Cable Arena where the rest of the convention has been held.
"We share the disappointment of over 65,000 people who signed up for community credentials to be there with the President in person," the convention's press release announcing the change said.
US Airways and United Airlines have issued waivers that allow passengers traveling from Charlotte on Friday to leave Thursday instead.
"Due to the impact that weather has had on the Democratic National Convention's event schedule in Charlotte, N.C., US Airways will provide its customers the flexibility to adjust their current travel plans at no additional cost," the waiver reads.
Complete details of the waivers are on United and US Airway's respective websites.
Charlotte is US Airways' largest hub, and the sixth busiest airport in the world in terms of operations, according to the airline.
American Airlines, Delta, JetBlue and Southwest Airlines, which also have flights in Charlotte, have not posted waivers.
US Airways also is warning passengers the city's airport will be crowded as convention attendees leave. They suggest passengers that are leaving on domestic flights arrive 2 hours before departure Thursday, and three hours before on Friday.
CNN Meteorologist Taylor Ward says Charlotte is experiencing scattered showers today and the weather Friday is looking better and not expected to have any impact on flights.
All of the airlines advise passengers to check their websites for the latest status of their flights.
