Sion to London is 842 km and about 1 h 29 min in the air, out of the Rhone valley to a London business-aviation field, normally on a light or midsize jet. The flying is the straightforward part. What has to be agreed first is the window at the mountain end on your particular date, because Sion is a mountain airfield rather than a metropolitan one and the conditions, the aircraft type and the hours all have a say in whether you leave from it. We publish no fixed starting figure for this route, and the reason is on the page rather than hidden behind an enquiry form.

Ninety minutes from the Valais to London, which on the last morning of a ski week is the difference between arriving home and arriving home late. Arranged 24/7, whole aircraft or single seats.
REQUEST A QUOTE842 km is barely more than a long lunch for a private jet, and it is the least of the three questions this route asks. The other two are local and seasonal: an airfield in the mountains has opinions about when it can work, and from December to March the whole of the Valais wants to leave on the same afternoon. There is a second, quieter peak from June to September, when the same valley is walked rather than skied.

The point of flying from Sion rather than from a larger Swiss airport is the drive you do not do beforehand. That is worth having, and it comes with a condition: a mountain field is more particular about weather, aircraft type and the hours it can work than a city one, so the departure is agreed before anything else on this route.
| Airport | Codes | Role on this route | What decides it |
|---|---|---|---|
| Sion | SIR | Departure | Where the sector begins, and the reason for flying it: a small airfield in the Rhone valley, closer to the Valais resorts than any larger airport. Tell us the day and the hour you want to be airborne and let us confirm what is genuinely available – conditions, aircraft type and the operating window all have a say, and there is the additional step that an aeroplane has to come in for you before it can take you out. We would rather tell you in advance than on the morning. |
| Geneva | GVA | Departure alternative | Not the plan, but the honest fallback. If the window at Sion cannot be confirmed on your date, or the weather closes the valley, Geneva keeps the trip whole at the cost of a longer drive at the start of the day – and on a departure that drive has to happen before the aircraft's slot, not after it. We say plainly which of the two your day supports rather than quoting the one that sounds better. |
| London Luton | LTN | Arrival | Your arrival as quoted here, and the field all the distances and times on this page are calculated to. Farnborough is the sensible alternative if your day ends west of London – tell us where you are going and we quote into the field that suits it rather than the one on the map. |
842 km sits comfortably inside the light jet band, so on distance alone the smallest cabin on this list would do. Two other things usually overrule it: what a party of skiers is carrying home, and what the airfield will accept on the day. Both are worth settling before the type is chosen.
The light jet that covers this sector easily, and through the winter one of the types most likely to be within reach of the Alps already. On a short hop out of the mountains it is often the sensible answer rather than the small one.
See the Phenom 300 ›A stand-up midsize cabin and the usual step up for a family or a group coming home after a week. Ninety minutes is short, but ski luggage is not, and this is where the hold stops being an afterthought.
See the Citation XLS+ ›The choice when the equipment rather than the party is the constraint: a full galley, a separate lavatory and the hold volume for skis, boards and boots for a group of eight.
See the Hawker 800XP ›All three types are on our own fleet pages. Which of them can be offered out of Sion on a given day depends on the conditions there as well as on availability – ask us and we will tell you straight.
We publish no fixed starting figure for Sion to London. On an Alpine route the same 842 km in the second week of February and the same 842 km in late April are two different purchases, and printing one number for both would be tidy rather than true.
What is published, by other people, are hourly rates for the aircraft class. Brokers quote EUR 4,600 to 9,700 per hour for European light and midsize jets (LunaJets, Europe, undated), others from EUR 2,900 to 3,500 per hour (Eurosky, 19.02.2026), and others USD 3,750 to 4,600 per hour (Paramount Business Jets, August 2026). Those are rates for a class of aeroplane, not prices for this pair. They are worth having in order to test a quotation and no use at all for constructing one – and on a short sector that gap is at its widest, because multiplying a rate by 1 h 29 accounts for none of the crew's day, neither the landing nor the handling at either end, and nothing at all of what it took to bring the aircraft into the valley in the first place. Those costs are much the same whether you fly for ninety minutes or three hours.
The second thing that moves the number on a departure is where the aeroplane has been. One that carried a party in the day before and would otherwise leave empty is a different proposition from one flown up from elsewhere purely to collect you. It is also worth asking what is already moving: in winter the European fleet drifts towards the Alps and back out again, and in the spring the leg running your way – outbound, away from the mountains – is where the saving lives if your dates bend at all.
The hourly rates above are third-party published figures for the aircraft class, not prices for this route, and they are shown so that you can check any quotation you receive, ours included. Only a written quotation from Diamond Executive Aero Services, against your dates, is a price. Call +357 95 119759, 24/7.
GET A FIRM PRICETwo seasons, and they are nothing like each other. December to March is the one everybody means when they ask about this route; June to September is the quieter half, when the same valley is walked and climbed instead.
| Period | What happens | What to do |
|---|---|---|
| December to March | The Alpine peak. The whole of Europe wants the same Sunday afternoon home, and the operating window at the mountain end is in shorter supply than the aircraft | Book weeks rather than days ahead for Christmas, New Year and the February half-terms. Give us the hour you want to be airborne, not only the date, so the window can be confirmed before the chalet is booked around it |
| April and May | The valley empties as the season ends and the fleet that spent the winter serving the Alps starts moving away again | The quietest and easiest weeks to buy this sector, and a good window in which to ask about a repositioning flight rather than a full charter – the fleet is going your way |
| June to September | The second peak, and a gentler one: walking, cycling and the summer in the mountains. Busy weekends rather than a solid four months | Two to three weeks ahead is usually enough. Long days help: the daylight that constrains a winter departure is not the problem it is in January |
| October and November | The pause between the two seasons, and the emptiest stretch of the year on this corridor | Short notice is realistic and the aircraft is rarely the obstacle. Confirm the departure window early all the same: out of season, what a mountain field can offer is a question worth asking rather than assuming |
Seasonality here describes the Alpine pattern on this corridor rather than a published seasonal index for this pair.
The journey home starts above the valley rather than on the apron, and the first leg of it is the piece most often left until too late. From the resort the way down is a car or a helicopter, depending on the resort, the hour and the snow – we arrange it alongside the flight rather than leaving you to find one at seven on a Sunday morning in February.
The outbound leg, published in full. Booking both halves together is what lets the operator plan the aircraft into the valley rather than hope for it.
