Haven't flown yet but one thing I just found out after booking a couple trips is
Currently, all Customers must check-in for their flight at the airport ticket counter. Please arrive early to receive your boarding pass prior to your flight.
It defeats the convenience of small airports if I have to show up early and stand in line for ckeckin plus small airports don't have much space or lounges for hanging out. I love convenience of BUR but terminal interior is absolutely awful and arriving 1.5 h early for morning flight from BUR is completely nuts.
Why they couldnt get online checkin going right away is beyond me. And KTN doesn't work with avelo yet based on bloggers notes but small places don't have much of precheck benefits anyways.
