The wheelchair was offered asa i presented myself, the staff was attentive, friendly and helpful. The check in was quick and i was delivered to my gate in a timely manner. My carryon bag did not fit under the aisle seat, but does fit under the middle seat. I had no access to my carryon as it had to go in the overhead bin. The wheelchair was available as i deplaned. The attendant was very helpful and friendly. I’ve noticed a big improvement in this service during the last few years. Thanks.🙏
