[QUOTE Strange that the OP didn't think to book Phoenix-Aguascalientes on CO (with a transfer at IAH)! A lot less hassle I'd've thought.

Many thanks Londinense and Bobsyouruncle.

CO is not an option for me - well not for a while yet until they join Star Alliance. I'm on a RTW redemption, in First and Business, taking in the UK, various points in Asia, LA, Vegas for US Election night (any suggestions???), Mexico, then home to Ireland. More info here Since that posting have amended the North American section to take in Vegas and Phoenix as well as LA

Cant wait..

Best wishes
