Online United Airlines Tickets Compare Airfares Deals & Discounts

One of the most frequently asked questions about Delta Air Lines is about the fare structure. With only two tiers, Delta's cabin experience is straightforward. With three tiers, it's carefully structured, with each fare level providing a different level of comfort, flexibility, and value.

• Basic Economy: The lowest cost option for cheap flight ticket — no options for seat selection, no changes, no upgrades, and last to board. Ideal for lighter, more mobile solo travelers.
• Main Cabin Economy: Standard economy with advance seat selection, carry-on bag and Delta's in-flight entertainment. The trusted daily option.
• Comfort+(Economy plus): Up to 6 inches of extra legroom with dedicated overhead bin space, priority boarding and complimentary snacks and drinks. The balance of economy and premium.
• Premium Select: Delta's premium economy class featuring wider reclined seats, higher meal service, amenity kits and priority boarding on long-haul international flights.
• Delta One: Fully lie-flat seats, chef-curated dining, access to Delta Sky Club lounge, dedicated flight attendants and priority on check-in and baggage. The highlight of the Delta experience.

Network Centered on Where You Really Need to Be. Not only does United have an extensive network, but it has deliberately created a network structure. Instead of focusing its resources on a few select major routes, it has developed a hub-and-spoke network structure that allows passengers from almost any city in the U.S. to conveniently access both domestic and international destinations, with seven major hub airports:

• Chicago O’Hare: Major hub airport for United. Gateway to Europe, Asia, and coast-to-coast flights. 
• Newark/New York City: United's primary East Coast hub and a major gateway to Europe and international destinations.  
• San Francisco: Major Pacific hub airport. United's primary Pacific gateway, offering extensive service to Asia and the Pacific region.  
• Los Angeles: Major West Coast hub airport. Transpacific and South American flights. 
• Houston (IAH): Latin America hub. Operates more than 50 destinations in South America. 
• Denver: Major hub airport for the Western U.S., growing hub connecting the coasts and internationally. 
• Washington Dulles: Major mid-Atlantic hub airport. Major European and government flights.
