There is supoosed to be electronic linkage between the airline and the US CBP, but it is not always available.I'm just back from another trip to the US. We both had to apply for new ESTA & I don't remember the application being anywhere near as detailed last time. I haven't seen it mentioned anywhere before, but both airlines we used (TG and OZ) required our ESTA approval details. I've never had this before, but they couldn't check us in without it. Luckily I was able to get onto the ESTA site to find the details when checking in in MEL, and then printed them out in the lounge, but it held us up for nearly 15 minutes extra at check in.
That is why I endeavour to always have a printed copy of my ESTA with me when travelling.
