Somebody didn't have a good in-flight experience!

Katie Holmes' sourpuss looked a bit like the angry cartoon face on her tote bag as she touched down at LAX, on Thursday. The casually-dress actress -- wearing red pants, a black and white plaid shirt and brown suede boots -- was carrying an interesting handbag for the flight. It was, perhaps, a projection of her mood, seeing as how she looked a bit down in the dumps!

EXCEPT when we asked her about rumored fiance Jamie Foxx! Suddenly she turned that frown upside down ... watch!
