Southwest Airlines is increasing its checked baggage fees by $10, with the first bag now costing $45 and the second bag $55. The move comes less than a year after the airline ended its long-standing 'bags fly free' policy, and is part of an effort to offset higher jet fuel costs that have spiked since the start of the Iran war in late February.

Why it matters

Southwest's decision to raise baggage fees marks a significant shift for the airline, which had long marketed its free checked bags as a key differentiator. The fee hike is the latest in a series of similar moves by U.S. carriers as they grapple with surging jet fuel prices in the wake of the Iran conflict, which has disrupted global oil supplies.

The details

Customers checking one bag will now pay $45, up from $35, while a second bag will cost $55, up from $45. Some travelers will still receive a free first checked bag, including certain loyalty-tier members, eligible co-branded credit card holders and active-duty military members. Southwest said the changes are 'part of an ongoing analysis of the business and against the evolving global backdrop'.

  • On May 2025, Southwest ended its decades-old policy of allowing passengers to check two bags for free.
  • On Wednesday, Delta Air Lines' higher baggage fees took effect.
  • Last week, JetBlue and United Airlines also raised their bag fees.
