The regional carriers have each announced plans to launch a Manchester-Newquay service.
Eastern’s year-round service will operate four times a week, starting from 23 October.
Flights will be operated by a BAE Jetstream 41 aircraft on Sundays, Mondays, Thursdays and Fridays.
Loganair, meanwhile, will launch a daily Manchester-Newquay service on 28 March next year using a 70-seat ATR72-600 aircraft.
Eastern said the move would "assist the recovery of UK regional economies" while Loganair said its move would help restore UK regional connectivity following the collapse of Flybe.
