Roundtrip Flight Deals at CheapOair

Roundtrip is where the deepest discounting sits, because airlines price return itineraries to fill both legs and an aggregator can mix carriers across the outbound and inbound where a single airline cannot. Code RT45 applies up to $45 off roundtrip bookings at CheapOair through 6 September. The practical technique with a roundtrip search is flexibility on the return rather than the departure — shifting the inbound by a day frequently moves the fare more than shifting the outbound does, because return legs on Sunday and Monday carry the heaviest business and leisure demand. Compare a few date combinations before applying the code.
