HOUSTON — A United Airlines Boeing 787 flight from London to Houston has been canceled because of apparent trouble with an indicator device.

United spokeswoman Mary Clark says Flight 125 on Tuesday from Heathrow Airport to George Bush Intercontinental Airport was canceled due to problems with a message indicator. Further details weren't immediately released. United Airlines is a unit of United Continental Holdings Inc.

United officials say the 211 passengers on the jet, which Boeing calls the Dreamliner, were being put on other flights Wednesday.

A United Boeing 787 bound from London to Houston on June 20 — also listed as Flight 125 — diverted to Newark, N.J., because of a low engine oil indicator.

Boeing Co.'s Dreamliner faces more scrutiny than normal because it was grounded for three months earlier this year amid concerns about overheating lithium-ion batteries.
