While passengers with full-fare first class tickets will still fly fee-free, beginning in July, passengers who upgrade will pay $20 each for their first and second checked bags.
According to Alaska's website, first class upgrade passengers who were confirmed on or before May 15 will not have to pay the new fee. Those who were confirmed on or after May 16 will pay the $20 as of July 10.
Airlines' fees have been making headlines for a while now. Carry-on fees, which Alaska charges, and charges to print boarding passes are just two examples of the hidden costs that have many travelers up in arms.
For the low down on the fees travelers now face, check out the slideshow below.
Back in 2010, American Airlines <a href="http://www.huffingtonpost.com/2010/02/08/american-airlines-to-char_n_454109.html" target="_hplink">started charging $8 for blankets</a>.
Ryanair Boarding Pass Fees
Songstress Lily Allen took to twitter to express anger over<a href="http://news.travel.aol.com/2011/06/06/lily-allen-twitter-ryanair-boarding-pass/" target="_hplink"> Ryanair's policy of charging passengers to print out their boarding passes</a>.
Spirit's Online Booking Fee
In November 2011, Spirit Airlines <a href="http://www.huffingtonpost.com/2011/11/14/spirit-airlines-raises-on_0_n_1093430.html" target="_hplink">raised its domestic "passenger usage fee" (aka online booking fee) from $8.99 to $16.99</a> each way.
Southwest Airlines <a href="http://www.huffingtonpost.com/2012/03/26/southwest-airlines-fees-fuel-costs_n_1381008.html" target="_hplink">raised its ticket prices by $4 to $10 to offset the high cost of jet fuel</a> in March 2012. Its subsidiary AirTran, plus United Airlines, Delta Air Lines, American Airlines, US Airways, Frontier Airlines and Virgin America followed suit.
Ryanair Emergency Row Fee
Ryanair found itself under investigation after <a href="http://www.huffingtonpost.com/2012/03/20/ryanair-in-hot-water-over_n_1366497.html" target="_hplink">instituting a 10 pound fee to sit in the emergency row</a>.
Allegiant Air's Carry-On Fee
In April 2012 the budget carrier announced a <a href="http://www.huffingtonpost.com/2012/04/02/allegiant-air-carry-on-fe_n_1397911.html" target="_hplink">$35 carry-on fee</a>.
Spirit's New Carry-On Fee
A month later, low-cost Spirit Airlines <a href="http://www.huffingtonpost.com/2012/05/02/spirit-airlines-carry-on-fee_n_1472508.html" target="_hplink">upped carry-on fees to as much as $100</a>.
Airlines Could Charge Extra For Seats Together
Late May 2012 saw airlines start to <a href="http://www.huffingtonpost.com/2012/05/21/airline-charges-seats_n_1533866.html" target="_hplink">reserve more window and aisle seats for passengers willing to pay extra</a>. This would make it it harder for friends and family members to sit next to each other.<br /> <br /> Sen. Chuck Schumer urged airlines to <a href="http://www.huffingtonpost.com/2012/05/27/chuck-schumer-airlines_n_1548794.html" target="_hplink">allow families with young children to sit together without paying extra</a>.
United's $100 Bag Fee
In June 2012, United <a href="http://www.huffingtonpost.com/2012/06/12/united-airlines-raises-international-bag-fee_n_1589223.html" target="_hplink">raised its fee for a second checked bag on trans-Atlantic flights to $100</a>. Delta had done the same a few months earlier.
Wizz Air's Carry-On Fee
Carry-on fees have finally hopped the pond. <a href="http://skift.com/2012/07/09/carry-on-bag-fee-spreading-wizz-air-charge-europe/" target="_hplink">European regional carrier Wizz Air instituted a 10 Euro (about $12) fee to use the overhead bins</a>. Bags that fit under the seats still fly free.
Credit Card Booking Fee
In August 2012, Airefarewatchdog called out <a href="http://www.huffingtonpost.com/george-hobica/the-latest-airline-fee-credit-card_b_1829396.html">Allegiant Airlines for charging more to book flights via credit card</a>.
Southwest Airlines' Early Boarding Fee
<a href="http://www.huffingtonpost.com/2013/01/22/southwest-airlines-fees_n_2525443.html?utm_hp_ref=travel#slide=more232494">Southwest passengers can pay $40 to be one of the first 15 people on the plane</a>, as of January 2013.
United Fare Increase
United Airlines announced in December 2012 that it would be raising domestic fares up to <a href="http://www.huffingtonpost.com/2012/10/10/united-airlines-raises-prices-10-dollars_n_1954864.html" target="_blank">$10 per round trip</a>. While the price bump is minimal, travelers looking for the best deal could be dissuaded from purchasing the slightly more expensive tickets.
One of the most profitable airlines in the U.S., <a href="http://www.huffingtonpost.com/2013/06/28/allegiant-air-fees_n_3516384.html" target="_blank">Allegiant Air</a> came into the spotlight for its length list of added-on fees. The budget airline is similar to Ryanair in wooing travelers with low-cost flights to small airports and tacking on hidden fees in every aspect of the flight. In addition to the run-of-the-mill luggage and seat-choice fees, Allegiant has fees for paying with a credit card ($8), using the overhead luggage compartments ($10-$25) and booking over the phone ($50!).

American Airline Fare Initiatives
In response to "nickle-and-diming" complaints, American Airlines introduced new <a href="http://www.huffingtonpost.com/george-hobica/american-airlines-new-fare_b_2312289.html" target="_blank">fare-bundling initiatives</a>. The options -- "choice essential" and "choice plus" -- offer an array of packaged perks for one set price, rather than a la carte. While many complained about the initiative, others saw it as a way to get more for your money.
United Premier Access
United Airlines rolled out "<a href="http://www.huffingtonpost.com/2013/03/01/united-premier-access-rip-off_n_2788513.html" target="_blank">Premier Access</a>" in March 2013. The program includes a designated check-in and security lines, and priority boarding and bagging handling. While the fees for the exclusive services only start at $9, travelers must <em>already</em> be elite customers.
Frontier Third-Party "Fees"
In May 2013, <a href="http://www.cntraveler.com/daily-traveler/2013/05/frontier-airlines-carry-on-fees-050213?MBID=twitter_" target="_blank">Frontier announced</a> that anyone purchasing a ticket through a third-party, such as travel agents or websites like Expedia, would be subject to additional fees. In reality, the fees are actually perks (such as carry-on luggage) Frontier only offers to travelers booking through the airline directly.
New Alaska Airline Fees
In July 2013, <a href="http://www.huffingtonpost.com/2013/07/09/alaska-airlines-fees_n_3568206.html" target="_blank">Alaska Airlines</a> raised its baggage checked fee from $20 per bag (for up to three bags) to $25 per bag for the first two bags, and $75 for an additional piece of luggage. The airline also upped it's ticket-change fee to $125.
