Got an email after completing booking saying I was 'eligible' to 'request' seating. Clicked through- never posted a cost or asked me to confirm purchase, didn't have to put in cc info (and I didn't think they could save my cc info without being asked) so I thought it was free. Then I get a charge in my card from Justfly and the airline. Customer service tells me its non-refundable and thats it. Total scam. Do not recommend for anyone. Pay the $10-$20 more to book on the airline site or another travel site!
