Hi all

Im looking to fly DUB-NYC in May, out in J back in Y and I'm looking for help.

Ive loads of options which are similarly priced such as DL, EI etc but want to stick to OneWorld as I'm BA Silver. So here's my questions;

AA fly direct but it's 752 & they're not all upgraded so thinking I should avoid on the outbound? That leaves AA 772, BA 744 or BA 788 via LHR. Flown upper deck 744 a few times, is this still best option? What's next best?

For the return should I just use AA752 as its overnight or should I go via LHR for more miles & tier points? If so, is 788 from EWR in Y that bad? Finally, as BA Silver is there any likelihood of an upgrade on the return and if so am I better to fly from JFK?

Thanks everyone
