Ticket pricing is a horrendously complex and messy business, with armies of programmers working overtime to extract every last cent from passengers. It all starts to make some kind of sense when you understand the airline's basic motive: Make people in a hurry pay. To achieve this end, the plane is divided up into fare classes (or buckets), some cheap, some expensive.

Grilling is one of the easiest and most enjoyable ways to cook almost anything. Grilling is often confused with barbecuing because it is typically done on an actual barbecue. While barbecuing is the technique of slow cooking food (chicken, ribs) over low, indirect heat, grilling is actually quite different. Grilling is the process of cooking 'hot and fast' over direct heat.
