Jet fuel

On the TV news this morning, I saw that Delta Airlines is canceling some of their flight schedule because of rising fuel costs. In order to lower costs, they're not raising fares (they've already done that); nor are they cutting back on "amenities" like in-flight meals and comfy pillows (already done that, too); they are just flat-out canceling flights.
If you have a ticket on one of these canceled flights.... too bad. Find another flight. Rearrange your schedule. Delta is trying to save money, and your convenience (or the minor detail that you purchased a ticket with the intention of actually flying on the date and time you'd planned) is not very important.

If they can use the "fuel cost" tactic without regret or consequence, why can't I??

Me: "Uh, fuel is too expensive this week. To save gas money, I'm only gonna be able to make it in on Tuesday and Thursday."
Boss: "I don't think you can do that."
Me: "Well, I apologize for any inconvenience..."
