On DL 1724 SLC to EWR on 6/20. Originally on a 737-900 and got a flight change alert that the new aircraft is a 737-500. Confirmed in the DL app that the flight is a 737-500. However, I do not see DL flying the 737-500 any longer in its aircraft fleet listing. Anyone have any insight? Is this a result of the recent Boeing 737 NG/Max wing repair bulletin??
