I've got to go to Europe for a couple days SEA-LHR or SEA-GCI. $305+ or $540+ respectively with 8 day stay or Saturday night stay. Or $1600-2400 for a two day stay.

Do I meet the terms of carriage if I SEA-GCI on AAticket1, then GCI-PDX on AAticket2 two days later, travel home by car or commuter airline, then after 9 days return PDX-GCI on ticket2, followed immediately by GCI-SEA on ticket1?

Or SEA-LHR on AAticket1, commuter flight to GCI, then two days later GCI-SEA on AAticket2, then 9 days later SEA-GCI on AAticket2, commuter flight back to LHR, then complete LHR-SEA on AAticket1?

As long as it is not a co-terminal, do I meet AA's requirements?
