With PVR being the airport code for Puerto Vallarta, Mexico. Recall that US Airways started nonstop flights to Puerto Vallarta and Cabo (SJD) in June 2010 with four flights a week to each. In March — most certainly not the slow season for tourist destinations in Mexico — both destinations dropped to Saturday only. Now US Airways isn’t showing any flights at all from CLT to PVR from January 2011 on. The Charlotte-Cabo service is still listed as Saturday only, at least for now. The airline still has multiple daily flights to both destinations from Phoenix.

The reason for the question mark in the headline is that sometimes airlines do screw up their out-month schedule filings, so there’s a slight chance that this is all a mistake. If it’s not a mistake, then it leaves Cabo as the only destination in Mexico, Central America, or the Caribbean the airline has successfully added from Charlotte since early 2005.
