But while the 25 for 25 promo may be impractical for many travelers (including myself), it could be a lucrative adventure in the right circumstances. In this articleHow the 25 for 25 promotion worksThe 25 for 25 promo offers three tiers of rewards based on how many unique JetBlue destinations you visit before the end of the year. Fly to 15 JetBlue destinations, earn 150,000 TrueBlue pointsFly to 20 JetBlue destinations, earn an additional 200,000 TrueBlue pointsFly to 25 JetBlue destinations, earn 25 years of Mosaic 1 elite statusThe rewards are cumulative, so completing all three tiers earns you 350,000 TrueBlue points and 25 years of Mosaic 1 status. The table below shows routing for each flight I chose, where destinations that count toward my 25 for 25 promotion total are written in bold. In terms of value alone, completing the first two tiers of the 25 for 25 promotion on this itinerary would yield a positive return, but not by much.
