Baby wearing while traveling

We are planning to take baby to meet family in California when he is a month and a half old (his great grandmom has dimentia and we want her to meet him while she still has some awareness of who he is!) we already arranged our flights and luckily found a direct one that's only 5 hrs! I plan on wearing baby so that he's protected more from the germs of airports and so he's more relaxed. I was wondering if any mommas have tips on traveling with a newborn and specifically which wraps or carriers you found to be best or terrible when going through airports!
