By Plane

Flying time from New York to Lisbon is about 6 1/2 hours; from Atlanta to Lisbon (with a stopover), it's 12 hours; from Los Angeles to Lisbon (with a stopover), it's 15 hours; and from Montreal or Toronto, it's 8 hours.

Major Airlines -- When it was established in 1946, TAP (tel. 800/221-7370; www.tap-airportugal.us), the national airline of Portugal, flew only between Lisbon and Angola and Mozambique (then Portuguese colonies). Today TAP flies to four continents and has one of the youngest fleets in the airline industry -- its aircraft have an average age of only 4 years. Its U.S. gateway is Newark, New Jersey. In Portugal, it flies to nine destinations, the most popular of which are Lisbon, Porto, and Faro.

TAP also has frequent flights on popular routes from major cities in western Europe. Its flights to Lisbon from London are an especially good deal; sometimes they're priced so attractively that one might combine a sojourn in England with an inexpensive side excursion to Portugal. TAP gives passengers the option of stopping midway across the Atlantic in the Azores, and it makes baggage transfers and seat reservations on connecting flights within Portugal much easier.

All this being said, TAP is just one of the major airlines that flies into Portugal, so be sure to shop around before booking. Studies have found that searches done between 2 and 4 months before travel tend to yield the best/lowest airfares. Try a website like Momondo or Kayak.

Regular Fares -- All airlines divide their calendar year into three seasons -- basic, shoulder, and peak -- whose dates might vary slightly from airline to airline. TAP's basic season is November 1 to December 14 and December 25 to March 31. The most expensive season is its peak season from June 1 to September 15, when passengers tend to solidly book most transatlantic flights. Other dates are shoulder season.

By Train

Thousands of traveling Brits (and foreigners visiting the U.K.) cross France and Spain by rail to begin their Portuguese holiday. If you opt for this, expect lots of worthwhile scenery, and be aware that you'll have to change trains in Paris.

Trains from London originate in Waterloo Station, pass through the Channel Tunnel, and arrive in Paris at Gare du Nord. Don't expect to merely cross over a railway platform to change trains: You'll have to traverse urban Paris, moving from Gare du Nord to Gare Montparnasse. You can do this for the cost of a Métro ticket, but if you have luggage, hiring a taxi makes the transit a lot easier. (Taxis line up near your point of arrival.) From Gare Montparnasse, the train continues through France but requires a change of equipment in Hendaye, on the Spanish-French border. It continues to Lisbon's Sta. Apolónia station. Total travel time for this itinerary is 22 hours, so we strongly recommend reserving a couchette (sleeping car). Budgeteers can save about 10% off fares by taking a slower, less convenient ferry across the English Channel. However, this option adds at least 5 hours, additional transfers, and many hassles at the docks on either side of the water, and will involve you in imbroglios that probably aren't worth the savings.

From Paris, the most luxurious way to reach Portugal is by the overnight Paris-Madrid Talgo express train. It leaves from Gare d'Austerlitz and arrives in Madrid's Chamartín Station, where you transfer to the Lisboa Express.

In Madrid, the Lusitania Express leaves the Atocha Station at 10:45pm and arrives in Lisbon at 8:15am; the 11pm train arrives in Lisbon at 8:40am.

Some of the most popular passes, including Inter-Rail and Euro Youth, are offered only to travelers under 26 years of age; these allow unlimited second-class travel through most European countries.

By Bus

There is no convenient bus service from other parts of Europe to Portugal. Flying, driving, and traveling by rail are the preferred transport methods. However, the buses that do make the trip -- say, from London or France -- offer somewhat lower prices (and less comfort) than equivalent journeys by rail.

The largest bus line in Europe, Eurolines Ltd., 52 Grosvenor Gardens, London SW1W 0UA (tel. 08717/818-177; www.eurolines.com), operates bus routes to Portugal that stop at several places in France (including Paris) and Spain along the way. Buses leave from London's Victoria Coach Station daily, travel by ferry across the English Channel, and arrive in Lisbon 37 hours later. Tickets from London to Lisbon cost £83 to £110 one-way and £188 round-trip.

Eurolines also offers service from London's Victoria Coach Station to Faro, in southern Portugal, every Monday, Wednesday, and Friday at 10pm. Arrival is 2 days later, after multiple stops and delays.
