CHEAP FLIGHTS You dont have to pay high prices for air travel any more. There are lots of alternatives to regular, full-priced plane tickets if you can plan far enough ahead. Here are a few of the options. "No extra" airlines charge very low prices for most flights. These airlines offer the same services as other airlines, but you sometimes have to pay extra for them. For example, you may have to pay for any food or drinks you have on the plane, and you may have to pay extra if you check baggage instead of carrying it on the plane. Seats on charter flights are usually sold as a package deal with hotel accommodations. You can get great prices on these charter flights, but occasionally you have to spend long hours waiting in airports because charter airlines often own only on or two planes, and one late flight means that all flights are late. Regular airlines may offer special rates if you book your flights in advance and fly on certain days of the week when they dont expect to have full planes. These special prices are called "super savers", and you have to ask for them when you call the airline. If you make any changes in your travel plans after you buy the ticket, you may have to pay a penalty.

If you share our anxieties about the suffering caused by the caging of battery hens, we would like you to put Barn or Free Range eggs on your shopping list too.

Free Range eggs are also laid by hens that TEXT enjoy the freedom of a hen-house, but have the added benefit of access to an outside run.
