Yeah, um, you don't get refunds for sitting next to idiots. If that were the case, the fat Canadian asshole that spilled over into my seat for the 6.5 hour flight from Detroit to Amsterdam would certainly qualify. Dealing with people like that is easy. You either do it yourself at your own peril, or you ask one of the flight attendants to square her away. You can be charged with a federal crime if you tell the FA's to fuck off, not to mention diverting the plane and removing you in handcuffs.
