Giving way - who ets preference from ATC
Hello,
the other day we (B737) were flying at our filed cruise level (think FL370). ATC asked us to descend to allow a converging 777 to overtake us, after which we could climb again.
Are there rules/guidelines who gets "right of way" in this scenario? I found it a bit strange. Maybe LoCo vs legacy, or narrow body vs wide body?
Tnx for answers!
