Traveling alone with baby

Hey mamas, I have a question. Maybe a couple lol I was planning on visiting my mother for a while in another state, and getting on an airplane with the baby. I’m very nervous about it, even though I have been on airplanes by myself. How did it go? What did you use for baby? My daughter is 6 months old and I don’t know if I should use a car seat, stroller, or use one of the wraps to hold baby. I just don’t want to forget any items in the airport and not be able to get it back lol. I’m just very nervous about it, please help with any of your experiences!
