Current bag prices are available here. One personal item that fits in the smaller sizer box (like a small backpack) is included with your ticket (Bare Fare™). Another personal item or anything larger like a standard carry-on or checked bag will need to be paid for.
PRO TIP: If you know you’re going to need a carry-on or a checked bag, buy it right when you book your flight to save major moola.
Check out size and weight limits for bags here, as well as embargo restrictions. Remember: You can bring one personal item and bring items like an umbrella, camera, infant diaper bag, assistive devices, outer garments (e.g., coats, hats and wraps), reading material and food for the flight for no additional charge. Neck and head pillows can be carried on the aircraft as long as they fit completely in your personal item bag.
In some cases wheelchairs, car seats and strollers may be checked or carried on free of charge.
