When did they start charging for transatlantic seat selection? Been 18 months since I flew the route but I don't recall them charging for any seats then or prior bar the exit rows.
Is this an IAG thing?
Have to say I am becoming less and less impressed. Their bag and seat fees are OTT as far as I'm concerned. No longer my first choice.
I've a horrible feeling you're being scammed and that if you wait until 24 hours before the flight to check in you'll probably find seats together for free. But it is a risk.
