If you experience a flight delay, the Enterprise airport location will honor the rental for the entire business day. There is no need to update the reservation unless the flight is going to be delayed until the next morning.
If you are going to arrive after closing, the pickup date and time should be changed to the next day.
When booking your reservation online or with an agent, include your airline and flight information. Providing us with your flight information allows us to serve you better because we can check with the airline to see if your flight has been delayed.
