We own the Citibank Prestige and the Chase Sapphire Reserve credit cards, and both allow us access into select airport lounges around the world. For our 3 hour wait at the Los Angeles Airport, we had the opportunity to hang out at the Air Canada Maple Leaf Lounge, even though we were flying on Southwest Airlines and in a completely different terminal. It was spacious, clean, and had a nice variety of simple lunch snack items to tide us over until dinner time.
