Did not get flight alert for a tail# when I should have

Is this unusual?

Yes, it’s unusual. Which alert did you expect to be triggered by what flight?

N144Z flying into MSO. It arrived last night - I rec’d no alert. Thanks

Your alert specifies airport KSMO instead of airport KMSO.

Also you have another alert with the airport as MSO; note it needs to be KMSO to work.

yikes! I need new glasses. Thank you for your quick response.
