Traveling with a fussy teething 3 1/2 month old

Tashiana

I'm so nervous tomorrow my husband and I will be flying to Miami from NY to visit his family for fathers day. My son has been extremely fussy and teething on top of it. Mainly hysterical when we're not holding him or he's napping. Idk what to do to make the flight easier on him and to decrease the chance of me being one of those mom's with a screaming baby on an airplane. Any advice ladies?
