Frontier is also pulling a fast one with minimal warning, adding fine print to its fees page, which details fees up to $10 extra for checked and carry-on luggage. These extra fees apply throughout the holiday season and also run into the peak Spring travel season. The exact periods run from November 19, 2015 to January 5, 2016; February 11, 2016 to April 4, 2016; and June 9, 2016 to August 16, 2016. It wouldn't at all surprising to hear these airlines also plan to leave a lump of coal in your seatback pocket.
