I hope to travel alone to visit DD in HI in Spring ..........and hope to find few dollars to send DH to visit her too someday in next couple of years. But because I could NOT afford to pay for an additional seat at the last minute, personally, I plan on taking him to airport and have them take a look at him. I do NOT care how that makes him feel. If he wants to fly, then he will have to have a pre-evaluation to determine if an extra seat is gonna be required. Yes, I have issues with this but that is the scoop. Sitting next ot a large person makes a 2 hr flight let alone a 5 hr flight just a miserable experience.
