I can live indefinitely with 2 sets of clothes, 1 to wear & 1 to wash, 1 extra pair of shoes, all in a day pack. I wouldn't necessarily WANT to do it, but I could, rather than stop flying if, say, the airlines reduced baggage limits to 10 pounds altogether. It's the same old story, I figure, if for any reason, you can't or won't travel (time, money, fed up, whatever), you just don't want to enough. One excuse is as good as another.
Good to hear about Norwegian. I repeated the exercise last night, looking for flights to Europe. Over $500 was the least I found in fees, that's using up 40,000 miles as well. I'd rather give it to Norwegian.
