I just picked up my first, and hopefully not last, 20-segment ticket here in NRT this morning. It is pretty funny to see the huge stack of paper tickets. When I went to CX to check in for the first flight, the agent was suitably impressed.
This trip will take me through August, including two return trips to my SEA home base, but I am thinking I should ticket a future trip by June even if travel won't begin until much later in the year. That's not a problem, is it? I may even try to do two, but that would be a considerable financial stretch.
