$600 million of them.

While Southwest Airlines has the strongest balance sheet in the industry, apparently even they are not taking the prospect of the current financial situation lightly.

The airline has borrowed $600 million, leveraging its ownership of 21 Boeing 737 aircraft, the airline disclosed yesterday.

Beth Harbin told Terry Maxon at the Dallas Morning News, “We felt it was wise to bolster our cash position with today’s soaring fuel prices and uncertainty in the economy and the credit market. We want to be prepared for whatever happens.”

At the end of the first quarter, Southwest had $3.12 billion in cash and short-term investments.

No word on whether or not Southwest CEO Gary Kelly is considering dressing up like one of these wacky squirrels next Halloween, but we think the idea has merit.
