My return from the Paris Air Show (CDG-EWR-MHT) on June 24th didn't post. I used the on-line request Sunday for missing credit (using e-ticket number) and the flights have been credited this morning.

Painless for sure... however I am glad that I both keep my boarding passes as well as the invoice (from our corporate travel tool) which shows the ticket number.

Hope the resolution for all will be as easy.
