Budget passenger carrier GoAir plans to add destinations such as Hanoi and Phnom Penh to its international network by the year-end, sources said. Sources said the airline, which is rapidly expanding its international presence, will also deploy capacity to Bhutan in the coming days. Till recently, the airline flew to just four international destinations — Phuket, Malé, Muscat and Abu Dhabi. Lately, it launched a slew of new international flights — Delhi-Abu Dhabi, Mumbai-Abu Dhabi, Mumbai-Muscat, Delhi-Bangkok and Kannur-Kuwait. However, some of these new international flights are being operated on re-allocated slots of Jet Airways. GoAir has the rights over these till September.
