Delta Air Lines is adding more flights out of Florida and the Caribbean as residents evacuate areas in the path of Hurricane Irma.

Atlanta-based Delta said it has added more than 3,000 seats on those routes for Thursday and Friday, a combination of additional flights and larger planes. The additions are commercial flights with seats for sale to customers, rather than humanitarian flights.

Delta has added flight capacity out of Miami, Fort Lauderdale, Orlando, Sarasota, Key West, Nassau and Freeport in the Bahamas, and Punta Cana, Dominican Republic.

Amid concerns about price gouging for various goods and services, Delta said it has capped fares in all cabins at $399 one way to and from southern Florida through Sept. 13, and is waiving fees for baggage and pets in cabins.
