Many pages took tens of seconds to load and had a single field to fill out, broken links to information, etc. I had to fill in my personal info three times, on different pages, with wildly different layouts and misspelled fields. It had to be done over four separate days, because two pages had 503 errors and a couple others told me to wait up to 5 business days for "procesing" or "processin" or other misspellings, though it only turned out to need a couple minutes or hours.
I watched my card for unexpected charges like a maniac as emails from different domains every time came in to inform me that I was still good to go. But the tickets came through fine, about 3 weeks later, less a week before my flight.
From reddit, I'm under the impression that this is a somewhat average experience.
