Spirit Airlines, which has been promoted as the low-budget airlines that offers fares as low as $9 each way, now charges nearly $34 to book a round-trip flight online.
The airline is also known as the one that boasts the most extensive lists of extra fees in the industry.
At the beginning of this month, Spirit raised the “passenger usage fee from $8.99 for one way domestic flights to $16.99, but the international flights decreased from $18.99 to $16.99.
The only way to avoid the fee is to buy a ticket at an airport counter. But as of Jan. 24, 2012, the airline will charge passengers $5 to print out a ticket at the airport counter.
