I didn't really ask for eticket numbers as I thought it was sufficient that they were able to locate our bookings without a problem, and to confirm seats. Accessing the information on Thai's and Swiss' website works but there is no mentioning of a different eticket number, and the reservation is still in our USDM profile - surely it would have been cancelled if it had failed to ticket by now, about ten days after making the booking?
I really wished checkmytrip or another gadget would work: Thai's flights booked through Lifemiles does so I guess this means that Avianca works with CMT/ Amadeus but US Air doesn't... any suggestions/ should I call TG and LX again?
a reservation can exist independently of a ticket.
however without a ticket number you will be refused travel. at worst case, an airline may review their flights and can (and do) cancel any reservation without a ticket number. this can happen at any time, not necessarily within 24, 72 or however many days.
once cancelled, you need to rely on having award inventory available to recreate your booking.
cancelling seats because a ticket number has not been received in time happens often enough on SQ and OZ for it to be an issue.
most recently this happened to my friend
just last weekend on a USDM ticket for travel on TG. changed flights from BKK-BRU-CDG to the direct BKK-CDG flight three months ago. called to reconfirm his booking three days prior and TG had no ticket number. he would have been denied travel.
being able to retrieve your booking, select seats, book the cook or do anything else with your reservation does not mean it has been ticketed.
the ticket number issued by USDM will be the same for all airlines, even though different airlines may have a separate PNR for you.
calling the airline and specifically asking if they have a ticket number against the booking takes a few seconds, but is invalubabke 'insurance'.
(note there are some airlines such as UA that will display the ticket number on their website when you access your booking. you don't need to call them as the ticket has already been listed.)
