It might, but don't panic if it does. Mine usually spikes, not because of noise but because my ears never seem to care much for the pressure changes. They don't "pop" right away so it makes my T seem louder for a little while, but as soon as they pop things go back to normal.
When I fly, I tend to take an over-the-counter decongestant and wear flight earplugs like earplanes of flitemates. Those cut down on a little sound and also help with the pressure changes. Make sure NOT to wear normal/closed ear plugs when ascending and descending. I also use bose noise-cancelling headphones for watching movies etc. - those things are amazing.
Most of all, have a safe flight, enjoy your vacation and don't stress
