Self-made millionaire Barbara Corcoran draws the line at a handful of splurges — and flying first class is one of them.

"I never spend money on a business class or first class plane seat," says real-estate mogul and "Shark Tank" judge Barbara Corcoran. "What I do instead, however," she explains, "is make my coach seat look better than all those suckers paying triple the price up in first class."

Check out her must-haves for enhancing your in-flight experience no matter where you're sitting:

• A starched napkin
• Two kinds of gourmet cheese (one hard and one soft)
• A bottle of wine (purchased at the airport after security). She jokes, "I don't want to wait for the stewardess to say, 'Would you like something to drink?' I'm already guzzling that wine!"
• Either a croissant or bread
• A piece of fruit
• All kinds of salami (Barbara's favorite)

Everyone from fellow coach passengers to first-class folks get jealous when she unwraps her snacks, she says. "I'm telling you, people look at me with hate." LOL!

Even Rach couldn't resist snacking on Barbara's treats before the show started!
