A worldwide computer glitch left British Airways customers stranded at Hartsfield-Jackson International Airport Tuesday.

After sitting on a plane for four hours, Mercilina Oladejo and daughter Charis, 3, learned they would be put up in an Atlanta hotel. Charis is supposed to start school in the United Kingdom this week.

They were among 20 travelers who were stuck at the airport or sent home overnight after the check-in system went down, according to Channel 2 Action News.
