HELP! What's my R/C number? Is it 00406373? Does that look like an RC?

We need to get an invoice from the travel agency Heather and Ozzie used for
my flights last week. I know the travel agent's name is Julie, but I don't
know the details. The agency is something like Vitol. I suspect Claudette
can give you the telephone number, etc. I would have gotten a receipt from
Continental, but the E ticket machine wasn't working.

I have the rest of the receipts.
