Frontier Airlines Promotion: US Domestic One-Ways Starting at $40/€37 (Incl. Seat Selection, Cabin Bag + 18kg Checked Bag)

The Covid-19 pandemic changed the face of America’s aviation industry in the long-run. Mere weeks ago, Southwest Airlines announced it would abandon core principles of its long-time, highly successful business model, because financial results cratered after 2019. At the same time, ultra low-cost-carries like Spirit Airlines and Frontier Airlines began selling premium seats. Frontier even began rebundling fares after years of upselling every little thing they could.

Currently, the Denver-based carrier is targeting disgruntled Southwest passengers with two promotions that are as out-of-character as Southwest’s sudden swerve. For flights until August 2025, Frontier sells economy tickets including a personal item, a cabin bag and a free standard seat selection for the lowest available price. Even better, by adding the code FREEBAG you can check a 18kg piece of luggage for free.

The promotions run until March 24, 2025, but the cheapest tickets may sell out earlier.

• 0$ Economy-Bundle:
  • Travel period: March 24 until August 18, 2025
  • Only on select flights
  • Includes:
    • Personal Item (47 x 35 x 20 cm)
    • Cabin bag (60 x 40 x 25 cm), up to 15 kg
    • Seat selection (standard seats)
    • No re-booking fee (the fare difference still has to be paid)
• Free checked bag:
  • Travel period: May 28 until August 18, 2025
  • Only on select direct flights
  • Enter the code FREEBAG before booking
  • Limited to 40 lbs = 18.1 kg (A 50 lbs bag comes with a $75 price-tag)

Both promotions end on March 24, 2025.

You can find US$40 (~€34) tickets in the economy fare with a 40lbs on the following routes (prices are one-way):

• San Francisco → Los Angeles
• Los Angeles → Phoenix
• Dallas → Phoenix
• Atlanta → New York
• Orlando → New York
• Orlando → Detroit
• Miami → Washington D.C.
• New York → Orlando
• New York → Raleigh/Durham
• Boston → Atlanta
• Philadelphia → Tampa
• Denver → El Paso

These are really competitive prices. Other airlines like Delta or United seldomly charge less, and even if they do – those fares don’t include goodies like checked bags or seat selection. Since Southwest won’t unbundle its fares before May 28, 2025, be sure to compare prices before purchasing a Frontier ticket.
