Yes, you can take a Double BOB stroller on an airplane, but you will almost certainly have to gate-check it rather than bring it into the cabin. Because a Double BOB (like the Revolution Flex Duallie) is far too large to fit in an overhead bin—even when folded—airline policies in 2026 require these oversized joggers to be tagged at the check-in counter or the gate and stored in the aircraft's hold. Most major airlines allow you to gate-check one stroller per child for free, which doesn't count against your baggage allowance. However, some "ultra-low-cost" carriers and certain international airlines have weight limits (often 20 lbs) for gate-checked items; since a Double BOB weighs roughly 33 lbs, you should verify with your specific airline to ensure they won't charge an "oversized" fee. To protect your investment from the rough handling of baggage systems, it is highly recommended to use a specialized padded travel bag for your Double BOB to prevent frame damage or fabric tears during transit.
