The supposed "feud" between Angelina Jolie and Jennifer Aniston is largely a tabloid construct these days, but chances are good both ladies are happy someone noticed they were booked on the same transatlantic flight -- and did something about it.

According to E! News, the previous and future Mrs. Brad Pitt were both set to fly first class from Los Angeles to London on the same British Airways flight Sunday night. And if an eagle-eyed employee hadn't noticed, that could've been a super awkward 11 hours for all involved.

Aniston's camp was reportedly notified, and they changed her flight to Monday instead, but sources say both she and Jolie "were blissfully unaware of the reason behind the switcheroo."

Just a guess, but maybe Jen used her extra day stateside to meet with her attorney -- because in other Aniston news, TMZ reports the 'We're the Millers' actress is being sued by a contractor who claims she racked up a $43K tab when his company built a back deck on her Bel Air home. His suit says she later claimed the work was shoddy, had it torn down, and now refuses to pay for it.
