Recently, Spirit Airlines was hit with a lawsuit alleging that it has made millions of dollars in sneaky Passenger Usage Fees tacked on to ticket prices.

And personal finance website NerdWallet says the carrier has raked in more than $140 million in fees since 2008 -- and that doesn't include what Spirit has made this year.

While the carrier may have collected that amount, we understand that doesn't mean they have the cash freely available to spend.

But in our times of austerity, it's fun to take a look at what the airline could buy if it did have the scratch to spare.
