I have to say I'm thankful for Verifly, has worked great for me for most of the times. Didn't need to visit the desk or talk to anyone at LPA yesterday. BA should advertise it more though, as I mentioned in some other thread, my friends flying OTP-LHR were told only Romanian issued certs are valid. They had never heard of Verifly, managed to explain it to them and guide them through setup just in time for them to upload Klarity certs and get their BPs.
As a comparison, saw off my travelling companion to LH flight out of LHR today morning. Despite her uploading all necessary and some unnecessary paperwork she couldn't get the BP and had to visit the desk, which was a right zoo. She was finally pulled out of the queue about 10 min before closing time, otherwise she would have missed the flight.
