Morning all... Please can someone do me the honours with a LX check.

ZRH to either ORD or MIA on 14/8 or 15/8.

Need three seats, ideally F but i'll slum it in C if I have to!

I'm having real problems with connecting US domestic flights from IAD and ORD (to MCO) showing available but various agents have told me they can see but they aren't released yet! Had several options lined up from IAD but they won't release.
