Hi Martin - as far as I understand SU is not working with myidtravel. They are, however, working with ID90 including who at some point in the future plan to facilitate interline eTicketing for ZED travel. If/once they do that SU should be able to issue eZED for travel on OAL but only on those airlines that accept interline eTickets for ZED. Some, like SK, LH and WN, can't or won't, so it's possible you won't be able to travel on them. Most airlines, however, will reciprocally implement IET so you should be well covered.

You cannot access myidtravel for ticketing unless your airline is a customer of their ticketing product. You can, however, access the site to create a flight listing on those airlines that use them for flight listing.
