Query regarding Aerlingus in particular.

Can you book an award BA codeshare, that includes EI connections. For Example, BFS->TEL (via LHR). Currently the avios calculator will not accept BFS->LHR (on EI metal) to work out avios needed.

If you can do the above, will it be available online, or only over the phone, and will the EI flight count as a domestic connection ?

In a similar vein, will BA codeshare flights commencing in DUB on EI be available for award booking (unlikely to be considered domestic). The Avios calculator will not accept DUB->LHR.

"other partners" page states:-
Flights booked under the British Airways code but operated by one of our codeshare partners, are eligible for mileage accrual and Tier Points but not redemption.
