If you care about your stroller and don't want to chance either renting strollers down there or needed to buy a new one, I wouldn't get just a cheap $20 bag but a nice substantial stroller bag like the JL Childress on or you can even get them with wheels to just roll the bag to the gate check area. My $300 stroller was utterly destroyed on the first airplane trip we took. We had a delay each way and each leg of the trip it was destroyed worse and worse, I couldn't believe it. The airline tried to reimburse me for all the damage done in the form of a free ticket, but after the horrible customer service, damage to the stroller, a stewardess actually stole my daughters toys from her stroller (another stewardess caught her) I never wanted to fly Delta again and my strollers are always in a bag now. I usually go through one bag every two trips as the rips and tears it sustains make it unusable, however I'd rather a $30 bag take the beating and not my $300-400 stroller!
