I flew 4 times to the US in the last 2 months, twice from Canada as I presume you will.
You are allowed a carry on plus one personal item. In this case, that would be the
camera bag. I use a Lowepro Nova 5 because it is the largest allowed camera bag
that counts a personal item. The dimension actually vary slightly by airline but the
common denominator is 36 linear inches. This means that length + width +depth
have to be 36" or less. Nova 5 is 14.9 x 9.5 x 8.9 = 33.3 linear inches.
