I am in the minority and found it more trouble than its worth. Probably because we only fly back at the end of school holidays, busiest days of the year. Done it twice, both times took around 1 hour, not fun in that heat.
I prefer to do online check in and arrive at airport 2-3 hours before flying, bag drop takes no more than 5 mins.
This August we will be flying back PE, is it the same(probably long again end of August) line as economy?
