Building on its largest-ever service to the Latin region this winter, Delta is enhancing flight frequencies from six of its U.S. hubs. This growth translates to a 30% increase in available seats compared to last year's winter season, with added frequencies to nine destinations in the region including Guatemala and Liberia, Costa Rica, in Central America, as well as San Juan, Puerto Rico.

Beyond that, it also creates a crucial gateway to the U.S. for customers, providing them with seamless onward connections to as many as 100 U.S. cities through Delta's largest hub in Atlanta.

Delta will begin flying these added Saturday routes seasonally starting Jan. 13. All of these routes will operate on varying aircraft including the Boeing 757-200, 737-900 and 737-800, all featuring First Class, Delta Comfort+ and Main Cabin.

In addition to more Saturday frequencies, Delta is also adding an extra trip from Seattle to Cancun that will depart on Fridays and return on Saturdays. This route will begin operating seasonally starting Dec. 22 on the Boeing 737-800.
