The crew was extremely helpful in finding my husband another seat, since he was using a cane on this trip and we had purchased exit seats due to him needing the extra leg room to extend his leg. The flight attendant was able to move another passenger so that my husband actual had a row by himself in which he could turn sideways and put his leg up if he needed to extend it. The only complaint would be the self-checking of baggage at McCarran. We and we noticed a couple of other groups, had some difficulty getting the scale to work. A couple service reps had to assist us all. One of the issues was that you had to stand a certain distance from the luggage scale/conveyor in order for it to work properly. Maybe tape outlining the area to stand would help? The other problem was that it scanned our IDs, but kept asking for us to input info; the rep overrode this so that our luggage would process.
