UAE and Saudia Arabia alone can justify this new planes ( probably they will add new routes)
This is a lucrative market for Greece ( wealthy Arab are making Athens a second home lately) and can be year around
Saudia is a promising new market
Emirates already have a codeshare agreement with A3
all this destination would be 4+ hours
I really hope that at least night flight out of Heathrow will see the new planes as well but as said by others here it’s just 3.30 hours
