However, experts adds, it won’t be easy. “Having one stop to European cities will pit the airline against other full-service carriers. Second, a lot of revenue comes from cargo, which will be minimal in a narrow body (aircraft). Without an advantage in capacity deployment, it would be difficult for IndiGo to emulate what they did in domestic travel,” says Ameya Joshi, founder of airline blog Network Thoughts.
IndiGo had changed its aircraft order book, to upgrade 125 of the A320 Neos to the larger variant, the A321 Neo. The latter would take around four hours to reach Baku or Tbilisi; it would be another four hours to London.
