Yes. Another option is to give up on the bug-filled tool and have AA’s specialist RTW desk do it - especially if you have an intercontinental AA flight somewhere in your itinerary (I’ve not tried without). I am doing an ex-OSL RTW bought that way shortly. Finnair is the first carrier but refused to assist with a RTW booking; and the tool would not correctly validate the route. AA were very professional and knowledgeable.
I've given up on the oneworld site's two booking options.. I have two questions: My first flights are CAI-CMN-DFW-ICT. Through Expert Flyer, I've found D inventory on CMN-DOH-DFW. The QR flight to DFW has an AA codeshare. Would the RTW desk likely look at this as an AA flight? (I can try to book TPAC on AA, too.)
If I try to find a travel agent to book this, will all future date changes have to go through that TA, or could I deal with AA, the airline I hope to be ticketing trip?
