Frequently asked questions
What size is a Spirit personal item?
Spirit Airlines gives the personal item maximum as 18 x 14 x 8 in / 45 x 35 x 20 cm on its own baggage page. Must fit entirely in the smaller sizer bin. Measure the bag packed, because a soft backpack that fits empty can bulge past the depth limit once it is full.
Can a backpack be a personal item on Spirit?
Yes, as long as it measures within 18 x 14 x 8 in / 45 x 35 x 20 cm when packed and fits under the seat in front of you. Look for listings that state an 18 x 14 x 8 inch or smaller size. Straps and bottle pockets count toward the size if they stick out.
What is the difference between a personal item and a carry-on on Spirit?
The carry-on goes in the overhead bin and is limited to 22 x 18 x 10 in / 56 x 46 x 25 cm; the personal item goes under the seat and is limited to 18 x 14 x 8 in / 45 x 35 x 20 cm. On Spirit’s cheapest fare only the personal item is free, which is why its size matters so much here.
Researched, not professional advice. Limits change and can vary by route and fare; the airline's own page is the final word.
