Do I need to exit Thailand before my TR visa expiration on November 2 if I am flying on that day?

Dear TVA fam. My tr visa expires on November 2. I will be doing a non b in Vientiane next week. If my tr visa expires on Nov 2 does that mean. I have to exist Thailand on any day before Nov 2 including Nov 2?I pose this question because I will be going from Chiang Mai to Bkk Don muang and then from Bkk to udon thank on November 2 via air Asia. Will arrive at the border around 2 p.m and I'll stamp out on November 2nd. I'm just scared immigration Don muang say something since my visa expires on Nov 2 and I'm traveling from Don muang to udon thani on November 2 to cross the land border in nong khai.
