I have 2 friends that are flying from California to Orlando together next month. I asked what they were doing about carseats and they said nothing they weren't worried as FL tickets dont carry over to Ca. I love these kids to death and hate seeing them unsafe They will be renting a car (or 2) there but no idea what they will get. I have kids ages and current seats but only can guess on sizes. Kiddos are 9 (currently rides in just seat belt she doesn't 5 step in my car not sure about her moms but parents dont care) maybe 80lbs and 4'8'' 5yrs old rides in lbb (turbo) maybe 40lbs and 43 inches 3yrs old rides harnessed in a evenflo chase he is tiny i'd guess 36" and 35 lbs and last 2yrs old rides in an evenflo chase is 35lbs and 34". Neither of the parents will rf The mom of the older ones doesn't make her kids ride in seats or belts all the time and is already been hit with 2 carseat tickets still hasn't got it through her head that her kids aren't safe!!!! I have no clue what the flight will allow. Any ideas?
