1. frontier

   The boundary was originally the landmark, that which marked off one piece of territory from another. The bound is the limit, marked or unmarked. Now, however, the difference between the two words has come to be simply one of usage. As regards territory, we speak of the boundaries of a nation or of an estate; the bounds of a college, a ball-ground, etc. Bounds may be used for all within the limits, boundary for the limiting line only. Boundary looks to that which is without; bound only to that which is within. Hence we speak of the bounds, not the boundaries, of a subject, of the universe, etc.; we say the students were forbidden to go beyond the bounds. A barrier is something that bars ingress or egress. A barrier may be a boundary, as was the Great Wall of China. Bourn, or bourne, is a poetical expression for bound or boundary. A border is a strip of land along the boundary. Edge is a sharp terminal line, as where river or ocean meets the land. Limit is now used almost wholly in the figurative sense; as, the limit of discussion, of time, of jurisdiction. Line is a military term; as, within the lines, or through the lines, of an army. Compare BARRIER; END.

5. George Hobica:

   Airline staff have been given a lot more power and have become policemen in the skies since 9-11, i think many are abusing that authority. Most of your rights and company policies—including when you are entitled to compensation for your inconvenience— are spelled out in the conditions of carriage which can be found on an airline’s website. The lengthy terms are filled with jargon and legalese, though they’re still worth eyeballing to understand the basics. Here are key reasons why an airline can bump you or otherwise make travel difficult for you: 1. The airline priced tickets for this flight too low.If a carrier realizes through its electronic reservation system that a non-stop flight fills too fast, that could indicate the ticket fares are too cheap. In such a case, your flight could be switched from a non-stop to a connecting flight. 2. The air marshal needs your seat. Because air marshals protect the public, they are sometimes seated in first class without prior warning. If one of them shows up and needs your seat, you can be bumped, reassigned to another seat, or put on the next available flight. And you won’t even get an explanation; the government doesn’t want you to blab that there’s an air marshal on board. 3. The carrier abandons the route. Consolidation within the industry has prompted some airlines to cut back on the number of available flights. Some, such as Allegiant Air and Frontier, have also abandoned routes that are no longer profitable. An airline should be required to put you on another carrier for the price you paid, says Hobica. But that’s not the case.
