Sun Country Airlines has revealed plans to further expand its network over the coming months amid hopes that increased availability of COVID-19 tests and vaccinations will kickstart air travel demand. The carrier is adding 16 new routes in total, nine of which will originate from its Minneapolis-St. Paul International (MSP) base. They include flights to Fairbanks (FAI), Houston (IAH), Indianapolis (IND) and Raleigh-Durham (RDU). Sun Country CEO Jude Bricker expressed cautious optimism that an upturn in leisure travel was in sight, buoyed by the rollout of vaccinations. US President Joe Biden has committed to overseeing 100 million vaccine doses administered in his first 100 days in office.
