Thank you Blott. I have not used this airline much, but will be travelling with them next May via Charlotte and like to be able to keep in touch. The Indianapolis connection that I would have liked allows only 95 minutes between flights and since I have to clear formalities at Charlotte, I decided to play safe and book a later connection - about 5 hours later. That is confirmed, but I intend to try and rush to the front of the Immigation queue at Charlotte and if I am clear within the hour, will request US Airways to fit me on the earlier flight if the gates are still open. It may not work this time (though I have successfully done it before at Buffalo) but I'll lose nothing by trying.
