I dont know if we are doing it yet or not, but since we dont have a stroller gate check bag, I tried to put our two mac volo's in my dad's softsided golf travel bag and they fit (like a zippered cover for a golf bag). We might do this or we just might send them under with nothing.... Our airline (allegiant) says strollers do NOT count towards luggage?
We are taking two volos instead of a double, I did buy the stroller connectors, they seem to do the job, dont know yet whether I will find them helpful or just another thing to carry around, but I am glad we are going with the two strollers. Our double just doesnt push very easily, so I would rather bring the singles. That, and the volos seats are wider than our double, so the kids have a little more wiggle room.
