2025 Guide to Checked Baggage Fees for Major U.S. Airlines

If you haven’t traveled in a while, you might be in for a surprise: Southwest Airlines, the champion of two free checked bags, has officially introduced a fee for your first checked bag. Yes, you read that right—things have changed! Below, I’ve put together a quick airline-by-airline breakdown of the newest baggage fees for 2025 so you know exactly what to expect (and how to avoid extra costs).

If you need to double-check the size rules for carry-ons, head over to my detailed post, Carry-On Sizes for Major Airlines (Dimensions & More).

2025 Baggage Fees Overview

I’ve compiled the most common fees for some of the biggest U.S. airlines. Fees might vary based on your route or ticket type, so always confirm with the airline directly before you pack!

Handy Tip: Weight limits typically max out at 50 lbs (unless you’re flying business or first class). If your bag is over the limit, you’ll get hit with that Overweight Fee. Oversize fees are extra if the bag’s total dimensions exceed the airline’s official limits (often 62 linear inches).

What’s Up with Southwest’s New Charges?

Since Southwest’s free-checked-bag policy was almost legendary, it’s a big deal they’ve started charging. You’ll now pay:

• $25 for your first checked bag

• $35 for your second checked bag

• $75 each if the bags are overweight or oversize

It’s not all doom and gloom, though—Southwest often runs promos or deals for frequent flyers. Keep an eye out, because they might waive or reduce fees for certain Rapid Rewards members from time to time.

How to Keep Baggage Fees in Check

1. Pack Wisely

   • Roll your clothes or use packing cubes so you can squeeze the most out of your suitcase space.

   • Weigh your bag at home (a cheap digital scale does wonders) to sidestep overweight charges.

2. Go Carry-On When You Can

   • A lot of airlines still let you bring one free carry-on, as long as it fits their size limits.

   • (Seriously, check out my Carry-On Sizes for Major Airlines guide if you haven’t already!)

3. Use Loyalty or Airline Credit Cards

   • Many credit cards linked to airlines will waive the first checked bag fee.

   • Elite status can save you money if you travel frequently.

4. Pay Ahead

   • Some airlines charge less if you pay online before arriving at the airport.

Packing smart at home helps avoid extra baggage fees later—measure, weigh, and organize before you fly.

Staying on Top of Fee Changes

Airlines love to tweak their policies when you least expect it. To avoid being blindsided:

• Check the Airline’s Website: Always your safest bet for up-to-date info.

• Sign Up for Alerts: Airline newsletters or apps will often announce policy shifts.

• Travel Forums & Blogs: Other travelers share real-time updates and personal experiences.

The days of free checked bags (especially with Southwest) are changing fast in 2025. By knowing these fees in advance and packing smart, you can save yourself a lot of hassle—and a chunk of change!
