NYC, here is the best thing about it. Well, I can't comment on LGA
, but here at CLE
it is a huge timesaver. Let's say you're leaving Saturday AM
, along with everyone else in Cleveland, on one of the many flights to Florida at that hour. The airport is a zoo, and the inside and outside luggage line is an hour long. Well lo and behold, there's an inside luggage line, dedicated to folks who already have a boarding pass, and that line has nobody in it.
So at peak times, it's a huge timesaver, with or without luggage. At non-hub airports, at non-peak times, then I'm not so sure.
One word of caution. If you check in, let's say the night before, and the next day you wake up too sick to travel, I believe your ticket is considered used. I'm not sure if you can cancel the segment by telephone. One of the airline agents said the one problem they have with the system is if someone checks in but then no-shows. That's why you hear some people paged many times just before a flight closes.
