Some planes do have larger seats where the escape door is over the wings. If that option is available, the check in counter should allocate those seats to the larger people. I have also seen this option available for a slightly higher price if you are making the booking online. I have travelled with a larger person, and he needed the extra belt that the airlines have for mums with small children. I feel very sad for the person who must have been so embarassed, the bully could do with some lessons in compassion. Marie.
