Pacifier weaning

Looking for some advice! My LO only uses/gets his pacifier in his bed and in the car (he’s always hated the car!). I’ve been trying to limit it in the car to when he’s tired only so he doesn’t think he gets it every time he gets in the car. I am a teacher and will be out of school in two weeks and want to get rid of the pacifier this summer. My concerns are, he’s teething and i think it helps with that (maybe not!) and we have three trips planned this summer. The first two are within the first two weeks after I’m done working (one is a long car ride, the other is a plane ride) and the next one is mid July (plane ride). My husband thinks we should get rid of them between the second and third trip but I’m worried about him not having one for take off and landing on the plane, and also making the trip miserable if he’s still having pacifier withdrawal/having a hard time sleeping somewhere other than home while we are gone (just being honest, I don’t want him to have it forever but I currently love my sleep!!!). What are your experiences/when would you get rid of it?
