Replacement flight or train bought yourself: claim the cost from SAS
A passenger can have a strong reimbursement claim for a self-bought replacement flight or train when SAS cancels a covered service, fails to provide rerouting at the earliest reasonable opportunity, and the passenger chooses a necessary, proportionate alternative. Contact SAS where practicable, preserve the routes and seats available at the time, avoid an unnecessary premium purchase and do not also accept reimbursement for the same transport without accounting for it.

Self-rerouting is evidence-intensive. Build the record before purchasing rather than trying to reconstruct availability later.
Save the final checkout screen as well as the search result. Headline fares can disappear, exclude baggage or change before payment, while the paid invoice proves the replacement cost actually incurred.
Before buying
| Action | Evidence |
|---|---|
| Ask SAS for earliest rerouting | Chat transcript, call log, desk record or app screen |
| Record the option offered | Departure, arrival, operator, cabin and airports |
| Search realistic alternatives | Timestamped results showing availability and total price |
| Check feasibility | Connection time, documents, baggage and airport transfer |
| Choose proportionately | Lowest reasonable route that meets the need, not merely the cheapest impossible route |
| Notify SAS | Written message that the passenger will self-reroute because no adequate option was supplied |
An emergency can make advance contact impossible. Explain the urgency and why waiting would defeat the journey.
Earliest opportunity is the legal benchmark
After a covered cancellation, Article 8 offers rerouting to the final destination at the earliest opportunity under comparable transport conditions. SAS cannot always limit the search to its own later service. A partner or competitor may be relevant when it materially improves arrival and has genuine availability.
Comparable does not mean identical. An economy passenger should not normally purchase Business merely because it is more comfortable. Business can be defensible if it is the only seat that meets an urgent, objectively documented need, but the evidence burden is higher.
The passenger must mitigate loss. A route with an unnecessary luxury stopover or distant arrival without onward transfer is less persuasive than a direct reasonable alternative.
Flight, train or mixed transport
A train can be appropriate for a regional journey when aviation disruption makes it faster or the airline offers no flight. Preserve the timetable, class and fare. Standard or equivalent rail class is easier to justify than a premium product unrelated to the original conditions.
Mixed transport may include a flight to a nearby airport followed by rail or bus. Record the complete arrival time and who should pay the transfer. If SAS proposes another airport, it has duties concerning onward transport in qualifying circumstances.
A rental car can be harder to recover because fuel, one-way fees and private use must be separated. Explain passenger count and why public transport was unavailable.
Refund and rerouting cannot be duplicated
Do not request the full unused SAS fare as if abandoning travel and also demand the entire replacement as rerouting without explaining how the remedies interact. Reimbursement and rerouting are alternative Article 8 choices for the same carriage.
If SAS automatically refunds after the passenger asked for rerouting, disclose the amount. The replacement claim may need to account for it. Fixed compensation for inconvenience remains separate and can coexist when notice, arrival and cause qualify.
A voucher also requires reconciliation. State whether it was used, rejected or accepted only for a distinct service.
When SAS offered a route
Compare arrival, not personal preference. A replacement leaving later but reaching the destination at a reasonable earliest time can satisfy the duty. Disliking a connection or carrier is not enough to justify a more expensive purchase.
The analysis changes when SAS's route arrives a day later and another available service arrives the same evening. Show the difference with timestamped results. Include check-in deadlines and realistic time to transfer.
If the offered route uses a lower cabin, the passenger can accept transport and claim statutory downgrade reimbursement separately rather than buying an avoidably expensive ticket.
Separate tickets and missed connections
SAS's rerouting duty normally follows the protected ticket. If a delayed SAS flight causes loss of an independently booked onward journey, that second fare is not automatically replacement transport under the first contract. Insurance, OTA promises or national damages rules may matter.
On one SAS ticket, the final destination includes the protected onward sectors. Make the one-PNR relationship explicit so SAS does not assess only the first flight.
The Copenhagen missed-connection guide explains the distinction.
Expenses around replacement travel
Meals and hotel while waiting belong in a care schedule. Ground transport required by a different airport belongs in another row. Baggage, paid seats and upgrade refunds have separate bases. Do not submit one unexplained total.
Keep itemised invoices, payment confirmation and proof the service was used. If currency conversion or card fees are claimed, show the actual charge.
Claim wording
Give a chronological account: disruption notice, SAS contact, options offered, alternatives available, passenger's choice, purchase and final arrival. Explain why the alternative was necessary and proportionate. Attach the original and replacement itineraries.
Request the exact replacement amount and identify any SAS refund already received. Then list fixed compensation and care separately. Use the SAS disruption-expense or appropriate claim route and preserve the reference.
If SAS rejects the cost by saying self-booking was unauthorised, ask it to address its own earliest-rerouting offer and the contemporaneous alternatives. The SAS escalation guide covers the next stage.
This practical test was reviewed on 26 August 2026. It does not guarantee every self-purchase; necessity, proportionality and the airline's response remain case-specific.
FAQ
Must I ask SAS before buying another flight?
Do so where practicable. If urgency prevents contact, document attempts, timing and why immediate purchase was necessary.
Can I buy Business if Economy is sold out?
Possibly when it is the only reasonable earliest option, but explain necessity and expect close proportionality review.
Can a train count as replacement transport?
Yes, particularly on a regional route where it reasonably reaches the final destination after SAS fails to reroute.
Can I claim both the unused ticket and replacement price?
Not as duplicate alternative remedies. Disclose any refund and explain the Article 8 choice while keeping fixed compensation separate.
What if SAS offered a flight the next day?
Compare it with real earlier alternatives. A much earlier proportionate route can support self-rerouting when SAS failed to provide it.
