WASHINGTON, DC (WUSA) -- You may want to travel a little lighter if you fly Frontier Airlines.

The air carrier says it will charge passengers up to $100 for a carry-on bag starting this summer.

But, if you pay for it ahead of time, it will only cost $25.

You can avoid all of the fees if you book your flight on the airline's website.

And if you want coffee, tea, juice or soda, be prepared to fork over two bucks.
