Yea so I was just wondering what was the smallest aircraft you used for a trans-pacific/atlantic crossing. I remember I used a 738 to do La Guardia to Bergen and a318 for London City-Shanon-New York JFK. Just recently I pushed the limits with a a321 from Tokyo Narita (RJAA) to Los Angelas. This really all depends on the winds and altitude.
In real life this probably can’t be possibly but in Infinite Flight it might be possible.
