I've missed connecting flights when the international flight arrives late.
It sucks. Spending more than an hour in an airport is really sucky, even in the executive lounge.
Do they serve free food and drinks in the executive lounge?
They have same drinks and snacks that will be found in the airline's Business Class section for that flight. So the international lounge has wine, beer, hard alky-hawl and mixers, and then sandwiches, pastries, and packaged nuts. For me the main draw is no-one is bogarting the wall socket, and you can sit without sharing an armrest.
They're nice, but you're still spending 5 hours in a single room, killing time.
