Have I got this right re Eurostar journeys?

Teapot42 · 16 Aug 2026

I'm not totally sure if this fits best in this sub or in the International Travel one, but we are planning on travelling to Avignon by train from Chesterfield.

Using a combination of TrainSplit and the Eurostar site, I get a price of £258 for the two of us to St Pancras (peak time journey unfortunately) then £547 to Avignon with a change in Paris, total £805

I was wondering, is there anything stopping us doing this with Interrail tickets? By my reckoning it's cheaper:
4 day Interrail €283 each, €35 x 4 Eurostar reservations, €10 x 4 TGV reservations, total €746 / £640

I think I'm right in saying there are no peak time restrictions using an Interrail in the UK, plus if EMR decide to strike or whatever we can use the same ticket to do CHD > DON > KGX rather than the farcical route via Tamworth EMR have arranged.

Have I missed anything? Not only are we saving money, but we've got 2 days travel in France on local services, three for an extra €35 each.

If this is correct, then a supplemental question - what happens if we are delayed and miss our reserved service? Will we be allowed on the next service (if it's a rail delay), or would we need to pay again for a new reservation?

It is worth checking whether Eurostar Interrail reservations are available for the date and time you want as there is a limited quota for them; that is the main thing that jumps out at me.

If there is still Eurostar Interrail passholder availability on trains that suit your journey then this sounds like a good plan. Indeed two expensive-ish legs in each direction are often all it takes for an Interrail pass to be cheaper. Interrail passholder availability on Eurostar services is tied to the prevailing public fare - if it's above a certain threshold then there is no availability.

Availability is often better in Eurostar Plus (former Standard Premier) if you buy a first class pass. You can check availability on the SNCB website, I suggest doing so before buying a pass. Also note that there is only a limited quota of €10 reservations on each TGV; once this sells out, the remaining seats can still be reserved with an Interrail pass but cost €20 instead. Annoying but not the end of the world.

You will be rebooked onto the next Eurostar/TGV service if you miss your connection in London or Paris due to train disruption, this is part of the HOTNAT and AJC agreements and it generally isn't an issue. However, note that these agreements do not entitle you to overnight accommodation if there's an overnight delay (e.g. because it's the last train of the day or no more trains that day have seats left), or to the food/drink or delay compensation you would get ordinarily if you had a through booking made on e.g. the Eurostar website.

This is because the legal position - at least on paper - is that you have separate contracts of carriage for each reservation-compulsory train you take on an Interrail pass, so effectively Eurostar/SNCF are 'being nice' by rebooking you. I have severe doubts as to whether this would hold up to scrutiny in court given that you have bought one pass, not multiple passes, and are showing a single barcode/ticket which lists all those trains, but that is the position they could try to revert to if it all goes Pete Tong. We have heard of Eurostar being difficult in terms of reimbursing expenses even when there are no connections involved, so in the interests of pragmatism I would allow plenty of time for the connections and make sure you're not connecting onto the last train of the day, where possible.

The Eurostar will also need to be on the same days as the domestic UK journies, as it will count towards the home country limits.

Teapot42 · 16 Aug 2026

There seems to be plenty of availability on all services - I've already checked, and the services we are aiming for and the following ones all have availability.

The journey will be done in one day - this is partly what makes the non-Interrail option expense, as we need to be at St Pancras around 10am to give 2 hours for delays and to check in. Also, coming back the Eurostar arrives around 4pm so we'd be in to the evening peak.

We don't seem to be near the last train of the day either way, but I'll double-check. We'd have liked to come back later, but planning on getting an EMR after 8pm doesn't seem a good idea at the moment.

Am I right in thinking that TER services don't need a reservation? Any travelling we do near Avignon is likely to be using these services.

Interrail is almost always cost-effective for journeys from beyond Greater London, provided you can get the Passholder fares when you want. I would budget EUR20 for the TGVs though as the cheaper fares are quota-controlled; even so, you are still in pocket

Yes, TERs are unreservable, except some longer distance ones serving Paris.
BTW I would consider routing via Lille rather than Paris, particularly for the northbound journey, if the times are convenient.

Does your pricing include CIV tickets for the Chesterfield-London leg? These do not have peak time restrictions, and are only valid for connecting to/from Eurostar.

I have done gone to France for the weekend using Interrail tickets, it was the 2023 Rugby World Cup so travel was a little pricey otherwise! Funny how this works when France is not usually greatly accommodating for Interrail travellers.

In this experience the Eurostar was delayed going into Paris so missed the connection to Nantes with no further trains available that evening. Eurostar booked everyone with onward connections into hotels, I got the first train to Nantes the following morning, and I was able to claim food expenses.

Hotel came with breakfast too, but still had to pay for the missed hotel in Nantes which I learnt that travel insurance did not cover. :'(

I too don't know how Eurostar could wiggle out of expenses and accommodation when on an Interrail ticket when it is as technically a through ticket with CIV protection. But I guess that does not mean they cannot try...

Regarding TER services, most do not require any reservations. There are a few (mainly to/from Paris on longer distance runs) that do, but generally these are quite cheap at around €1.50 or €1.70 per seat.

CIV tickets have less onerous time restrictions than regular tickets, but the Euro High Saver (effectively the equivalent of an Off-Peak Return) is still only valid to arrive in London from 10:11, which may be too late for the OP's needs.

I'd not thought to check CIV tickets, but as you note it's cutting things fine. I can save £80 but that only leaves about 90 minutes change which feels tight, especially considering recent EMR issues.

Plus, is still more expensive than the Interrail.
