Big mess at Heathrow Terminal 5.

On seeing Niagara Falls, Oscar Wilde proclaimed it "the second major disappointment of American married life." These days, the biggest disappointment in every travelers life is Terminal 5 at Heathrow.

By end of day Saturday, British Airways had cancelled nearly 250 flights, affecting 14,000 passengers. Flights departed with no baggage whatsoever. Planes sat on the tarmac for hours. Baggage handlers couldn't keep up with the new, automated system. And parking was no where to be found.

San Carlos de Bariloche and Argentina's Patagonia.

If you haven't been to Argentina yet, chances are it's on your short list. The charms of Buenos Aires are one of travel's worst-kept secrets.

But Argentina is one of the most beautiful countries in the world. So even those who are just planning to pop down for a city visit should add Patagonia and the Lakes district to their itinerary.

San Carlos de Bariloche, a two-hour flight from Buenos Aires, makes an easy gateway. The town, which looks like a Swiss village, is underwhelming - you'll see all there is to see in a couple of hours. But the location on Lake Nahuel Huapi is beautiful.

If you're going to Dublin, there are several places where you can sample the best Irish dairy products.
