BA will check through on separate tickets with another oneworld carrier assuming you have a valid connection, so if it is CDG-XXX-SEA where XXX is not LHR then they should be able to check it through for you.
2A - 2C minimum connection time is 90 minutes, so BA will not through check if you only have 80 minutes, so you would need to clear security, collect bags, check in for your IB/AA flight before checkin closes. Think you will want a longer connection time..
**-** II 1.30 TRM 2A - 2C
Thanks Nux! ^
That is definitely not what I wanted to hear; my problem is I'll be coming off a late flight the evening before so need to find a way to get to CDG early enough in the morning.
Was the "II 1.30 TRM 2A - 2C" code from expertflyer or can I find it somewhere else? I don't suppose you know whether AirFrance can check it through from London as their flight would give me a 100 minute window. I'd rather not fly with them as I'm pretty unconvinced by their safety record but I suspect that is the only way to get to Paris by 9.30am.
Thanks!
