Hard question to answer as each airline is slightly different.
The Cinebags Production Bag is: 27.5"x16.5"x11.5"
That's a total of: 55.5 inches (with side and front pockets empty)
Likely too large for many airlines as 45 inches and 50 inches seems to be standard. Some have a 55 inch limit and you could get away with that. I purchased it for local use primarily and would go to the backpack or hard case for flight.
