I asked someone if what was on my phone would work they said yes. So I waited in tsa for over a hr. Then they said it wouldnt and to go.back downstairs. I asked the people how to work the machine and they never told me. Then they said itd take 30 min to print a ticket. So I ended up missing my flight and not getting on another. I had to book with another airline because this one wouldnt do nothing for me but put me on standby... wont fly with this company again!
