We're booked (F) on BA0098 next week. MMB shows it to be a 777, which is what I had expected.

Orbitz shows the flight as using a 747, which I believe BA does use for the summer, but sometime in September they switch back to a 777.

I contacted Youfirst, and they told me it was a 747; however the wording of the response was such that if they had said "777" instead of "747" it would have all made sense. They said they did not know how Orbitz got the information that it was not a 747, when in fact Orbitz said it was a 747.

So I sent an "are you sure?" email back, and the response was yes, it will be a 747.

I'll take them at their word.

I still wonder which a/c we'll be flying on.
