Mexican low-cost carrier Avolar is flying again, just days after being grounded by aviation officials. Mexico's Communications and Transport Ministry grounded the carrier, saying it owed $13.3 million in fees dating to 2005 for using Mexican airspace.
But a Mexican court ruled that Avolar could resume operations while it challenges the fees.
Avolar isn't the only no-frills Mexican airline under pressure to pay overdue airspace fees.
Regulators last week also grounded charter airline Nova Air for unpaid airspace fees. Houston-based ExpressJet avoided suspension last month after it paid $5.2 million in late charges and back fees for Mexican fly rights.
Meanwhile, low-cost airline Aerocalifornia, which also was suspended last month for failing to pay back fees totaling $26 million, is still grounded.
Aerocalifornia's future is uncertain, as low-cost rival Interjet last month purchased Aerocalifornia's rights to operate at Mexico City's airport.
