Round-Trip vs. One-Way Flights

On February 16, 2025 By newsroom Topic: Traveler buyers guide


1. Key Definitions

  • Round-Trip Flight: One ticket includes travel from Point A to Point B and back.
  • One-Way Flight: Separate tickets for each leg of the journey (e.g., A to B and B to A booked separately).

2. Booking with Cash: What to Know

  • Domestic Flights:
  • Usually Same Price: A round-trip and two one-way flights generally cost the same in the U.S.
  • Tip: Consider two one-way tickets for easier management if plans change.

  • International Flights:

  • Round-Trip Is Cheaper: Often much more affordable than booking two one-way flights.
  • Example: A Washington D.C. to Frankfurt round-trip was $1,783, while two one-way tickets totaled $3,110.

3. Booking with Points or Miles

  • Flexibility with One-Way Awards:
  • Two one-way award flights offer more flexibility to modify plans.
  • However, some airlines (e.g., Delta) charge fewer miles for round-trip award bookings.

  • Watch Taxes and Fees:

  • Some regions (e.g., Europe) have higher fees for one-way award tickets. Example: Delta charges 74,000 miles + $220 fees for two one-ways but 50,000 miles + $85 fees for a round trip.

4. Open-Jaw Flights: A Third Option

  • What Is It?: Flying into one city and returning from another (e.g., into Budapest and out of Munich).
  • Cost Savings: Often priced similarly to round-trip tickets, making it cheaper than two one-ways.

5. Factors to Consider

  • Change Fees:
  • Many airlines (especially in the U.S.) have eliminated change fees for paid and award tickets.
  • However, mileage programs vary—check policies if flexibility matters.

  • Competition:

  • Routes with competition often have similar pricing for one-way and round-trip tickets.

6. Tips for Booking Smarter

  • Always Compare Costs: Check prices for round-trip, two one-ways, and open-jaw flights.
  • Account for Taxes and Fees: These can significantly affect award ticket costs, especially internationally.
  • Use Loyalty Programs Wisely: Explore whether your miles stretch further with round-trip or one-way bookings.
  • Stay Flexible: For uncertain plans, one-way flights might provide peace of mind.

Bottom Line:
- Domestic Travel: Round-trip and one-way flights often cost the same.
- International Travel: Round-trip is usually the better deal, but open-jaw flights can save money and offer convenience.
- Award Travel: Consider flexibility and fees when choosing between one-way and round-trip options.
