Airport/Cities/Countrys

You haven't got any airports in iceland or greenland so for me thats my first suggestion
Another one is what many people said is airports instead of cities like instead of london, Gatwick, Heathrow, London City, Luton, Stansted
and more airports you should add is
Hurghada (EGYPT)
Sharm El sheikh (EGYPT)
Luxor (EGYPT)
Bournemouth(ENGLAND)
Exeter(ENGLAND)
Bristol(ENGLAND)
Edinburg(UK)
Southampton(ENGLAND)
Bodrum(TURKEY)
Izmir(TURKEY)
Antalya(TURKEY)
Dalaman(TURKEY)
Ibiza
Malaga
Maldieves
Barbados
