Ski train vs flying: what actually makes sense

Nobody is really asking whether trains are nicer than planes. They are asking whether the train version of their trip costs more, takes a day off the holiday, and works with the people they are travelling with. The honest answer is that it depends on where you live, how many of you there are, and which resort you have picked, and that the balance has shifted enough in the last few years that the old assumptions are worth re-testing.

Flying wins on the headline fare and loses on everything bolted to it. A cheap seat plus hold luggage, ski carriage, seat selection, airport parking or a train to the airport, and a resort transfer at the far end adds up to a number that rarely resembles the price you first saw. Rail fares move the other way: the advance price is often high looking but largely complete, since skis usually travel free and the station is frequently in or near the resort valley.

Booking behaviour matters more than the mode. Rail released months ahead is competitive with a flight booked late; rail booked late is not competitive with anything. For a family of four the calculation tilts toward rail more often than for a solo traveller, because baggage and transfer costs scale per person while a car hire or private transfer does not.

Compare door to door and the gap narrows sharply, but it does not close. A flight to an Alpine airport is short; the two hours before it and the transfer after it are not. Rail removes the airport entirely and often lands you within sight of the lifts, at the cost of a longer journey that you spend sitting down, with a table, moving.

The overnight services change the arithmetic completely, because the journey happens in hours you were going to lose anyway. The counterpoint is equally real: a poor night's sleep on a moving train is a poor first day on the snow, and if your resort needs a change plus a bus at the end, the train's home advantage disappears.

Rail is at its best with small children, heavy kit and a group that can tolerate a long day. You keep your luggage with you, everyone can move about, and nothing depends on a minibus driver finding your chalet in the dark. It is at its worst when you are coming from somewhere without a good connection to the network, when you only have a long weekend, or when the resort you want sits up a valley the railway never reached.

Flying is at its best for short trips, awkward starting points and resorts that sit close to an airport. Transfer time is the thing to check first here: a 45 minute transfer and a three hour transfer are two completely different holidays flown the same way. Our snow sure resorts guide is the other side of the same decision, since the highest resorts are usually the furthest up a valley.

Rail is the lower emission option for this kind of journey, and it is not close. That is a fact worth stating plainly and then leaving alone, because the moralising version of this argument helps nobody and tends to ignore that not everybody has a realistic rail option. If the emissions matter to you, the useful framing is not guilt but planning: fewer, longer trips beat frequent short ones regardless of how you travel, and a resort you can reach by train is worth weighting in the decision before you book rather than regretting afterwards.

Take the train when you have a week or more, when you are travelling as a family or group with a lot of kit, when your resort sits on or near a line, and when you can book far enough ahead to get the fares that make it competitive. It also tends to win outright for anyone within reasonable reach of the direct seasonal services.

Fly when the trip is short, when your starting point is badly connected by rail, when the resort is close to an airport, or when the total cost genuinely comes out lower once you have added the extras honestly. The trap is comparing an all in rail fare against a stripped out flight fare and calling it a comparison.

A third option deserves more attention than it gets: fly to the nearest airport and take public transport in. Several Alpine valleys have good rail or coach links from the airport that cost a fraction of a private transfer and remove the worst part of the journey.
