I'm pretty sure this is not even close to accurate. $131M a quarter in aircraft rent? That's enough to rent about fifty large airliners, a small fraction of their fleet.

Aircraft rent or ownership is usually about one fourth of an airline operating cost. It's one precent in this chat, which of obviously WAY off.

Edit: I fixed a typo in my original reply, not I see in their actual finance disclosure that this chart missed aircraft acquisitions for $1B, which is not a small sum.
