I'm flying from IAD to NAP with a connection in MUC on UA902/4050 in late June.

The IAD flight arrives in Munich at 8:00am on Saturday morning, and the connection to Naples is at 9:10am. Is this enough time to make the flight?

The next Naples flight isn't until afternoon. Worried also if I miss the earlier flight that later flights will be sold out since this is the middle of Summer.

Appreicate any guidance.

Thanks.
