Just be aware that you may have issues with the interpretation of the Asia transit rules. You are traveling SWP-ASIA-EUROPE-NA-ASIA-SWP. I am assuming your second visit through Asia is planned as transit only. I know some people have had success in ticketing such a routing, but it depends on the interpretation of the rules.
If you were only transiting Asia the first time between SWP and EUROPE, and then visiting Asia on the return between NA and SWP, no problem. But visiting Asia between SWP and EUROPE and then transiting between NA and SWP depends on how one interprets the association of the word OR in the rules.
The rule regarding inter-continental departures states:
2 PERMITTED IN ASIA, 1 MUST BE A TRANSIT
WITHOUT STOPOVER OR ON DIRECT SINGLE PLANE
SERVICE BETWEEN THE SOUTHWEST PACIFIC AND
EUROPE.
The intent of this rule is to only permit the second transit when traveling between SWP and EUROPE. However, if you interpret the OR as referring either:
- transit without stopover, or
- direct single plane service between SWP and Europe
then your routing is valid. However, if it is interpreted as:
- transit without stopover, or
- single plane service
between SWP and Europe
Then it is not valid. I believe the second is the intent of the rule, but we know several people have been successful in convincing the ticketing agent that the first is a valid interpretation.
I just want to make sure you are prepared in case you run into this argument when it comes time to ticket the itinerary. Have you side of the argument ready to be presented.
