- American Airlines – Competitive Fares and Extensive Routes
As one of the largest carriers in the world, American Airlines combines global connectivity with affordable options for every traveller. While it’s not always labelled a “budget airline,” American’s extensive flight network and flexible fare classes often make it one of the best low-cost airlines for domestic and international routes.
Why American Airlines Offers Great Value:
- Frequent promotional fares and seasonal sales.
- Basic Economy tickets for cost-conscious travellers.
- Extensive domestic network covering 350+ destinations.
- Competitive international routes with affordable one-way deals.
For travellers seeking the best airline for international travel from the US, American Airlines offers an excellent mix of affordability and comfort, especially on routes to Europe, South America, and Asia.
- Delta Airlines – Comfort Meets Affordability
Delta Airlines consistently ranks among the top US carriers for service quality — and its fare options make it equally appealing to budget travelers. From discounted domestic flights to low-cost international connections, Delta proves that flying on a major airline doesn’t have to break the bank.
Key Benefits of Flying with Delta:
- Basic Economy and Main Cabin tickets designed for affordability.
- Regular discounts via Delta’s “SkyMiles Deals” page.

Delta’s frequent flash deals and loyalty rewards make it one of the cheapest airlines in the US for travelers who value both savings and reliability.
- Ethiopian Airlines – Affordable International Travel from the US
For travelers seeking low-cost international options, Ethiopian Airlines offers some of the most affordable fares among global carriers operating from the United States. Known for its strong service record and extensive African network, Ethiopian connects major US cities to destinations across Africa, the Middle East, and Asia.
Why Ethiopian Airlines Is a Smart Choice:
- Competitive international fares from major US hubs like New York, Washington D.C., and Chicago.

- Southwest Airlines – America’s Best Low-Cost Airline
When it comes to budget-friendly flying, Southwest Airlines remains a true pioneer among super discount airlines in the United States. Known for its transparent pricing and customer-first policies, Southwest eliminates many of the hidden fees that other carriers charge.
What Makes Southwest Stand Out:
- Two free checked bags on every flight.
- No change or cancellation fees.
- Open seating policy and quick boarding process.
- Frequent low-fare sales and early-bird discounts.
Southwest operates an extensive domestic network across more than 100 cities in the US, along with flights to Mexico, Central America, and the Caribbean. It’s one of the best low-cost airlines for families, leisure travellers, and frequent flairs who prefer flexibility.
- United Airlines – Global Reach with Budget Options
United Airlines combines the reliability of a legacy carrier with flexible pricing options that appeal to budget-conscious travellers. Through its “Basic Economy” fares, United makes flying affordable without compromising safety or quality.
