JetBlue Airways is reporting a small but surprising profit for the second quarter.

Relaxed restrictions for international travelers took effect on Sunday in the United States.

Worcester1012 via Wikimedia Commons(CNN) - JetBlue Airways is following its rivals by rolling out a new basic economy fare. Customers can bring carry-ons, and, as with most other classes of tickets, Blue Basic fliers will have to pay for checked baggage. JetBlue first announced it would develop a basic economy fare more than a year ago. The airline said in its third-quarter earnings report it expects to generate an additional $150 million in revenue from Blue Basic. Basic economy first began with ultra-low-cost carriers, including Spirit, before eventually being adopted by major airlines, including Delta, United and American Airlines.
