As of today, airfare advertising rules in the United States have changed. Airlines and ticket agents must now include mandatory taxes, government-imposed fees and fuel surcharges in the airfares they advertise.

It's important to note that airfares have not increased overnight; what has changed is how these airfares and their associated fees and taxes must be displayed to consumers.

In addition, a few important changes to existing rules will now permit passengers to cancel or change their reservations within 24 hours without incurring a penalty, under specific conditions, and provide passengers with information about flight cancellations, flight diversions, flight delays and other non-mandatory fees, such as checked-baggage fees.

Yogodo Hall, built in 1994, is part of the Senso-ji temple complex in Tokyo's Asakusa district. Senso-ji is an important Buddhist temple, Tokyo's oldest, which was built to house a golden statue of bodhisattva Kannon, the goddess of mercy and kindness, found by two fishermen in 628 A. D. The statue is hidden from view by long-established tradition.

Yogodo Hall was built to commemorate the 1,200th anniversary of Ennin's birth. Ennin was a Buddhist priest who visited Senso-ji and felt inspired to create a copy of the hidden statue of bodhisattva Kannon that could be displayed and worshipped. Inside Yogodo Hall are statues of bodhisattva Kannon and eight Buddhas. The Buddhas are believed to protect the 12 animals of the Chinese zodiac (dragon, monkey, ox, and so forth), and, thus, to protect the people born in each of those years.

Do you know any frequent fliers? Perhaps you're one yourself. One thing I have noticed about travelers who fly often (and I know many) is that they sometimes feel frustrated when their fellow passengers' actions slow down the airport security screening and airplane boarding processes.

While Emily Post could never have envisioned today's air travel situation (full-body scans, pat-downs, checked baggage fees, etc.), she certainly would have encouraged airline passengers to plan ahead and to be considerate of their fellow travelers. Today's frequent fliers tend to do just that; they pack and prepare so that they spend as little time as possible in security lines and boarding queues.

It all comes down to air travel etiquette. If most air travelers prepare in advance and know how to get through security and board their airplanes quickly, every passenger can find space for carry-on baggage and enjoy an on-time departure. Once in the air, the common rules of politeness apply, with a few air travel-specific additions.

You can see carved stones all over Ireland. Some are at famous places, like Newgrange and Knowth, while others, like this one, are found in small towns. This stone carving of King David and his harp stands next to a road in Carndonagh, County Donegal, near the town's pride and joy, the Donagh Cross, which dates to the 7th century.

All of Ireland is like this. Even the smallest towns have something special to offer, and places that are at times swarming with tourists have quiet spots where you can take walks and discover the best of Ireland.

The nice part is, you can plan a trip to any part of Ireland and find an out-of-the-way town or village to explore. You can see remnants of ancient dolmens, ring forts and standing stones all over the country. You may need an Ordnance Survey map to find them, but they are there. Sure, you should see the Book of Kells and the Ring of Kerry, but save a bit of time for the smaller sights of "undiscovered" Ireland. You'll be glad you did.
