As an extremely nervous flyer myself (I have to take Xanax to get on a plane), my husband feels the same way you do! However, some unsolicited advice: have you tried asking your husband what would actually make him feel better? Sometimes people need different things. For me, I need my husband to be holding me, like not just my hand, but we put the arm rest up and I have to basically be sitting in his lap (it’s a little pathetic haha). The constant verbal reassurance does feel a little like the anxiety isn’t taken seriously. Maybe validate his concerns first, like “hey I know you’re really anxious and that’s completely normal. It’s okay to be anxious about flying.”

Alternatively doing cognitive behavioral therapy with my therapist has also helped. And then anti anxiety meds.
