Thanks for the welcome and useful info.

Based on that, I will use *A Silver lane to check in, ask nicely and smile sweetly...... and be prepared to pay my $200 on the day. If E+ is sold out, so be it.

Glad I am not alone in thinking 1.20 mins is very short time to get through immigration, customs and security and onto the next flight. Guess I should just prepare to sprint through ORD.
