I made it back to IAH, so I also can be taken off the "stuck" list.
Iberia not so bad, in the back of the airbus but they got me to Miami. No dedicated line for GOES (another story) their customs is a mess.
Collected my bag and then sent it thru to Houston (had been tagged all the legs to IAH).
Upgraded on last flight MIA-IAH (thank you Continental !) was a nice way to land home in Houston.
No bag....it was apparently never transferred to Continental in Miami. I guess that's another story also if/when I get it.
Good luck to everyone else getting to their destinations !
