Bangladesh has barred SpiceJet from using its airspace as the budget carrier is yet to repay pending dues, according to sources.
With the Bangladesh airspace not being available, the airline is taking longer routes for some of its flights
from Kolkata, including to Guwahati.
When contacted, a SpiceJet spokesperson on Thursday said the airline was in regular dialogue with the relevant authorities on operational and procedural matters, including navigation-related charges.
