I don't know if this was unusual or not but when our full flight from SXM landed in Atlanta last night about 10 pm, people had to walk down the airplane ramp to get to wheelchairs.,,seemed like that would have been terrible for many. Then when we got into the concourse, we saw that there were half a dozen people or more sitting in chairs waiting for someone to push them. Since our flight was delayed a bit, immigration in our concourse had already closed, so we had to hike the whole way to the next concourse, a walk of quite a distance. I noticed several workers pushing 2 chairs each that whole way. One poor guy was pushing a couple each in a wheelchair, then had to grab a luggage cart to accumulate his clients several large suitcases to get through customs before dropping the luggage. I was guessing the basic issue was a lack of workers especially that late in the evening.
