Fares from CAI going westward have also been affected by the loss of possibility to get transcon in A, just like the ex-EU fares. A favourable ex-EU, like OTP, could have 3 SH+ before the IC flight, and then adding 1 leg >2000miles and 1 <2000 thereafter will be hard to beat in any other direction.
Just as some of us have combined two iteneraries going to HNL/LAX/PHX/SFO with an excursion to the Carribbean/Central or northern part of South America, I think we'll see more of this even going eastward.
There are in recent history, and presently, availabilities that make two C OW offers meet at the same hub, like AMS/LHR-BKK and BKK-TPE/DEL.
