United Airlines is planning a major technology update that will take down its online reservation system early Wednesday.
The carrier is urging passengers with flights scheduled to depart on Wednesday to check in via United's website or mobile app on Tuesday to avoid encountering problems. United expects the outage to last roughly four and a half hours, beginning Wednesday at 2:30 a.m. EDT and lasting until 6 a.m. EDT.
An alert on United's homepage informs travelers that it is "conducting a planned technology upgrade" and that many of its web and app services will not be available during that time, including for employees of the airline.
United is modernizing its aging mainframe flight reservation system, known as Shares. The upgrade requires the airline to transfer reservation data from its current data center in North Carolina to a more high-tech facility in Chicago that the airline said will improve reliability.
Here's what United customers should know about United's reservation system upgrade.

Washington — President Trump said early Monday that he is postponing airstrikes on Iran's power plants after "very good and productive conversations" over the last two days about reopening the Strait of Hormuz. However, Iran's foreign ministry denied any such talks. Claire Day contributed to this report. In:
