What size and weight limits apply to bike cases?

Southwest’s practical thresholds for bike travel are:

  • Standard checked bag: ≤ 62 linear inches and ≤ 50 lbs.

  • Oversize (63–80 in): ≤ 50 lbs — treated as a checked bag (no extra sports fee).

  • Oversize (81–100 in): ≤ 50 lbs — $75 sports-equipment fee.

  • Overweight: 51–70 lbs → $100 surcharge; 71–100 lbs → $200 surcharge.
    Bags that exceed both oversize and overweight limits may incur multiple fees.

What type of bike case should I use?

Southwest accepts non-motorized bicycles packed in a hard case, soft case, or cardboard bike box. Compact travel cases (for example, the Orucase B2) often stay under 80 linear inches, which is the easiest way to avoid the $75 sports fee.

Tips for Flying with a Bike on Southwest

  • Keep it compact: Aim to keep your packed bike under 80 linear inches and 50 lbs to avoid extra fees.

  • Pack for protection: Secure the derailleur, wrap the frame, remove pedals, and turn handlebars sideways.

  • Pre-weigh & measure: Measure your packed case before leaving home to avoid surprises at check-in.

  • Arrive early: Allow extra time for special-item processing.

  • Bring documentation: A screenshot or printed copy of Southwest’s sports-equipment policy can help if an agent is unsure.

  • Be courteous: A friendly, prepared approach at the counter often speeds things along.

Summary

Southwest remains a strong option for cyclists in 2026. If you pack into a compact case (under 80" and 50 lbs), your bike can travel with minimal added cost — usually only the standard checked-bag fee. Larger cases are accepted for a reasonable $75 sports-equipment charge, and overweight rules are clearly tiered. With careful packing and early check-in, Southwest is still one of the more predictable and affordable U.S. carriers for flying with a bike.
