This is great. But airports are super busy and crowded these days. Imagine all the extra people if everyone took advantage of this I don’t remember how it looked back in the day when you didn’t need Gateside.
for smaller airports, it won't matter, my local airport has four gates, the terminal is maybe 300 feet end to end, so everyone currently waits outside of security, but it's like 10-20 folks. the few that make it to the gate won't matter at all.
