I booked a ticket on expedia. Expedia tells me that the e-ticket has been issued and gives me an e-ticket # (starting with 236, so a BD ticket) but the ticket number does not appear in checkmytrip. I know that cmt won't display ticket # for paper tickets but normally does for e-tickets. Should I be concerned? This is a straightforward BD return ticket, so no SQ-like problems in sight, but still...
