So I've never tried to upgrade going over the pond. I'm a week out from my flight (PHL-LGW) and there's 9 seats in Envoy available. I believe 7 days out means all the CPs have upgraded.

Would this seem like a decent shot to use a Space Available cert? I'll be connecting from BDL so I'll be at PHL 3 hours early to try and ask nicely.

May have a chance, but I think CP's clear at the 3 day window for across the pond.
