www.checkmytrip.com does NOT work for Delta bookings (at least mine, sorry) - the record locators DL gives to me only work on their website.

Do I have to ask DL to quote a second (hidden) record locator to look the booking up on checkmytrip or has DL blocked access to its bookings for checkmytrip ???

I frequently look up on checkmytrip bookings with all European Airlines - no problem, but once I wish to access a booking made by a US carrier - out of luck !

Thanks for any clarification.
