I think this is old information; current policy::
We know that your baggage doesn't always fit neatly into a suitcase or regular-sized bag. That's why we accommodate baggage of all shapes and sizes. When you arrive at the airport baggage counter, we will determine if your item requires special care, and/or additional fees. Each special item counts as one bag.
You can bring most sports equipment with you on your trip, though extra baggage fees may apply to oversized or overweight items. If you don't see your item below, then normal baggage allowances, fees and handling policies apply.
