When I asked for wheel chair assistance as requested on line the individual walking around told me it will come after check in. One flight cancelled and one delayed made the line for bag drop very long and I cannot stand too long or walk too far! I’m 76 with knee replacement, obvious by the scar visible with short pants. Not appreciated and against the law in the US for priority seniors! I finally got the assistance after I checked in and complained I left from Gate 5 far from the counters. Except for this the flight was great
