Just to clarify. According to CXAGENTS.COM the ticketing deadline rules only apply to economy class tickets.

It's a strange change though. If you are issuing the ticket Open (as is still permitted as far as I can see, except for up to the first international segment) then only that first flight or two counts, and I don't see how they can police this - I would normally make that reservation ahead of time, but it's a simple reservation in M (now L). I could issue any of a number of types of ticket nearer the time for that fare class. Are they really going to say "Sorry Mr Christep - you made you reservation more than X days ago and therefore we can't issue a OW ticket for it"?

By the way CXAGENTS is also showing a change to the Circle Trip Explorer tickets, bringing them into line with the OWExplorer and allowing no more than two stopovers in the continent of origin, and max four segments in each of Africa, Asia, SWP and Europe/ME, with the same restriction on only two "long Europe" segments.
