TrueBlue status runs on Tiles, which replaced Mosaic-Qualifying Points. Mosaic 1 at 50 tiles, Mosaic 2 at 100, Mosaic 3 at 150 and Mosaic 4 at 250. A tile comes from every $100 of JetBlue travel or every $1,000 of card spending.
Below Mosaic, JetBlue runs Perks You Pick at 10, 20, 30 and 40 tiles — reward choices rather than status. Status earned in a year is held for the rest of that year and all of the next; tiles themselves reset at each calendar year end.
Points earning is 3x base on flights and 1x on Base fares, plus 3 more when booked on jetblue.com, and a Mosaic bonus of 3, 3, 4 and 5 by tier.
TrueBlue points never expire — one of the few programs to say so outright. JetBlue prices award seats against the cash fare and publishes no award chart.
