Flying with my 22 month old for the first time

Hey! I’m flying with my 22 month old for the first time next week and it’ll just be me and her. We did buy her own seat so not on my lap. Do you mom’s bring a car seat on the plane for your toddler to fly in? Buy airline restraints instead? Just use the regular seat belt? Gate check stroller and car seat? Check car seat at the check in desk with other luggage? We have a Chico travel system stroller and car seat as well as umbrella stroller as options. Looking for any and all advice on traveling by plane with toddler! Thanks in advance! 🤪
