American Airlines often provides the most frequent connections between Charlotte Douglas International Airport (CLT) and Gulf Coast destinations, with partner networks that offer one-stop itineraries to Northwest Florida Beaches International Airport (ECP). Delta Air Lines typically routes through Atlanta (ATL), offering competitive fares and occasional seasonal nonstops. United Airlines may provide one-stop service through its hubs, sometimes offering lower fares for flexible itineraries. In October, compare baggage allowances (basic economy vs main cabin), loyalty perks, and total travel time: American may offer better direct access from CLT, while Delta can offer smooth connections through ATL. CTA: Compare price, travel times, and baggage rules across carriers before booking your October CLT to ECP flight to ensure the best travel experience.
