How To speak with live person on United Airlines

Southwest Airlines offers two options within the same day flight change service:
Same-day confirmed changes: If there is a seat available in the passenger’s originally booked fare class, then the passenger is allowed to change his/her tickets for a confirmed seat on a new flight. This service is complimentary for the Gold Medallion, Platinum and Diamond members.
Same-day standby: Passenger can choose to wait for a seat on an earlier flight if there is no option of same-day confirmed changes. The change fee will only be charged when the passenger gets a seat on the requested flight
