High Altitude Passenger Flights

Can Somebody please help me.

A couple of nights ago I tracked an Air Dubai 737 heading west (to Dubai) over I R A N at around 52000 ft was this an error or are “normal” Boeing 737’s able to get to that altutude?

Looks like Wikipedia puts the service ceiling at FL410.

bad data, no way a 737 is getting that high.
