Spirit Airlines is getting set to hike one of its optional fees.
The ultra low-cost carrier is doubling the cost of agent-printed boarding passes starting April 16, according to information posted on its website.
Passengers who don't print their own boarding passes before heading to the airport, will now have to fork over $10 for each pass issued by a Spirit agent at check-in, instead of the previous $5 charge.
In an email confirming the fee increase Wednesday, Spirit spokeswoman Misty Pinson said: "We encourage customers to save time and money by printing their boarding passes before arriving to the airport."
Travelers may still be able to avoid the fee as at last check, printing a boarding pass from a Spirit airport kiosk was still free. Last summer the airline nixed plans to implement a $2 fee for kiosk-printed passes.
In January 2012, the Miramar-based carrier started charging passengers for boarding passes issued by an agent.
