How much would you expect to pay for this flight?

[antietam]

London to New York

then

Home from Miami 2 weeks later

During Summer school Hols 2020


So far seen

BA direct to NYC on 25 July 2020
Iberia indirect to London (via Madrid) on August 9 2020 (12hrs 30mins Duration)

£558 PP which seems very good to me

Would you wait for better flight routing and lower prices.
I wanted to go a bit later in the hols but flight prices will dictate.
These are the first cheaper flights i have seen and am i just being impatient.
How much would you pay?

Thanks
