Flying with an infant

B

Ladiessss, I'm a FTM & next week I'm going ok a plane with my 5 month old in my lap! M husband will go as far as he can but after that I'm on my own. How can I do it to make it as easy on me as possible? I use a snap n go with his car seat so that my stroller/car seat. Is that smarter than bringing an individual car seat? I'm thinking of just taking my diaper bag as a carry on and only my rolling luggage to check so I'm not with too many thing but advice is welcome. Thanks y'all (:
