Personal item

One personal item up to 18 x 14 x 8 inches is included on every fare. This is smaller than most carriers' personal item allowance and is enforced at the gate with a sizer.

Carry-on bag

A full-size carry-on is NOT included in the base Go fare and must be purchased. The price rises at every step: cheapest during booking, more at online check-in, more at the airport counter, and most at the gate. Buying at booking is the single biggest money-saver on Spirit. Maximum dimensions: 22 x 18 x 10 inches including handles and wheels.

First checked bag

Purchased separately, priced dynamically by route and demand, cheapest at the time of booking.

Second checked bag

Priced higher than the first bag, again cheapest at booking.

Weight limits

40 lbs (18 kg) per checked bag — ten pounds lower than the industry standard 50 lbs, and the most common source of unexpected charges on Spirit.

Overweight bag charges

Charges apply above 40 lbs and escalate steeply through 50, 70 and 100 lbs.

Oversize bag charges

Over 62 linear inches attracts an oversize charge.

Who gets bags free

Free Spirit Gold members and Spirit credit cardholders receive baggage allowances. Bundled fares include bags.

Sports and special equipment

Sports equipment is accepted but priced as oversize in most cases, which erodes the fare advantage considerably.
