JSX offers double rewards for flights through August

Members of the JSX loyalty program can now earn double rewards.

Normal rewards are a 5% credit toward future purchases.

During the sale, you receive 10% of your purchase price in credits.

The offer is valid for all flights booked by July 31 and flown by Aug. 31, 2026.

Rewards are automatically applied for Club JSX members.

Rewards are calculated solely on base fare.

Earlier this week, JSX was rated as the best U.S. airline for the third year in a row by readers of Travel + Leisure.
