A flight diverted to another airport, like a Tel Aviv–Vienna flight that was reportedly diverted to Sofia after a threat, according to unconfirmed information, can throw an entire long-haul itinerary off course. This article explains when EU Regulation 261/2004 applies, what the airline must provide you on the spot, what changes when the cause is security-related, and how to keep your documents and file a claim.
A Flight Diverted After a Threat: What Are We Talking About?
The case that serves as the starting point for this article is a Tel Aviv–Vienna flight diverted to Sofia after a threat against the aircraft. The details of this event have not been confirmed by an official source, so we do not repeat them here. What matters for you is what follows: a diversion can lead to a significant delay, a cancellation, or the inability to continue your trip, with missed connections and nights spent improvising.
The reference text on the European side is Regulation (EC) No 261/2004. It aims to ensure a high level of passenger protection by establishing common rules on compensation and assistance in cases of denied boarding, cancellation, or long delay of a flight[1].
When EU Rights Apply
The regulation covers two situations: passengers departing from an airport located in the EU, and passengers departing from a non-EU country to an EU airport, provided the operating air carrier is a European airline[1]. If you depart from a non-EU country, only flights operated by EU carriers count for compensation rights in the event of a long arrival delay at your final destination[2].
Two conditions also apply: a confirmed reservation for the flight in question, and check-in at the time stated in advance or, failing that, no later than 45 minutes before the published departure time. This second condition does not apply in the case of a cancellation[1].
For a flight outside the regulation's scope (for example, a non-EU airline departing from a third country), this file cannot detail your rights. For a flight operated by a non-EU airline to the EU, you may have rights under the legislation of the country where the airline is registered[3]; check with the authorities of that country.
Your Immediate Rights: Assistance and Care
While you wait, the airline must provide you with free assistance[2]. In practice, care includes refreshments and meal options, hotel accommodation, transport between the airport and the place of accommodation, and the option of making two free phone calls or sending two emails[1].
If an overnight stay is necessary, you are entitled to accommodation and round-trip transport between the airport and the hotel[2]. If you paid for meals and refreshments yourself because no assistance was provided, the airline must reimburse you, provided those expenses were necessary, appropriate, and reasonable[2]. So keep every receipt.
This assistance remains due even in extraordinary circumstances: the carrier must still provide you with a meal or accommodation while you wait[3]. Persons with reduced mobility, their accompanying persons, and unaccompanied children are entitled to this care as soon as possible, regardless of the length of the delay[4].
Refund, Rerouting, or Return Flight
In case of cancellation, you always have the right to one of these options: a refund of the ticket, rerouting or a return flight, plus assistance[3]. The regulation puts it this way: refund of the ticket within seven days, or a return flight to the initial departure point, or rerouting to the final destination[1].
Rerouting can also take place at a later date of your choosing, subject to seat availability and under comparable transport conditions[4]. This is useful if you would rather stay a few days at your destination than head home right away.
If the airline fails to meet its obligation to offer rerouting or a return flight under comparable conditions, the Your Europe page refers you to your refund rights[2]; consult it for the details of each case.
If the airline offers you a flight to a different airport than the one planned, in a city or region served by several airports, it must cover the transfer costs between the arrival airport and the originally planned airport, or another nearby destination agreed with you[4]. A flight diverted to an airport that does not serve the same city or region is considered cancelled: you have the same rights as in the event of a cancellation[3].
Threats, Security and Extraordinary Circumstances: What Changes for Compensation
This is the point that directly concerns a diversion linked to a threat. Among the extraordinary circumstances that limit the airline's obligations, the regulation cites political instability, weather conditions incompatible with the flight, security risks, unforeseen technical defects affecting flight safety, and certain strikes[4]. The Your Europe page also indicates that acts of sabotage or terrorism may be considered exceptional circumstances[3].
However, the airline is not automatically exempt: it must prove that the cancellation was due to extraordinary circumstances that could not have been avoided even if all reasonable measures had been taken[4]. For a delay, it must demonstrate this, for example by providing extracts from documents[2].
Outside extraordinary circumstances, the fixed compensation is €250 for flights of 1,500 km or less, €400 for intra-EU flights over 1,500 km and other flights of 1,500 to 3,500 km, and €600 for all other flights[1]. In the event of a delay, if you reach your final destination 3 hours or more late, you can claim this compensation, unless the delay was caused by extraordinary circumstances[1].
In practice, for a diversion caused by a security threat: assistance remains available to you; the choice between a refund and rerouting is guaranteed if the flight is cancelled; and the fixed compensation may be refused if the airline proves an extraordinary circumstance. Whether a specific event falls into this category depends on the facts; the file does not allow us to decide this for the Tel Aviv–Vienna flight.

Traps, Scams and Points to Watch
No trap or scam specific to diversions (fake agents, fake claim websites) is documented in the sources for this file; we therefore write none. Here are the conditions and exceptions, confirmed by the official texts, that most often cause travelers to lose their rights.
- Rerouting and delay: if the airline offers you rerouting and you reach your final destination late, compensation may be reduced by 50%, according to the table on the Your Europe page[2].
- Ticket with several connecting flights: in case of downgrading, a refund is only possible for the flight concerned, not for the entire journey[2].
- Departure from outside the EU: only flights operated by EU airlines qualify for compensation for a significant delay upon arrival at the final destination[2].
- Lost or damaged baggage: the claim must be made in writing to the airline within 7 days, or within 21 days after baggage collection if it was delayed[2].
- Deadline for going to court: it depends on national legislation and varies across EU countries[3]. Contact the national enforcement body in the country concerned.
- Ticket sold by one airline but flight operated by another: the operating airline is responsible in case of a problem[3].
- Complaint to the DGAC: its action is independent of the resolution of individual compensation and refund requests with airlines[5]. Reporting to it therefore does not replace your claim to the airline.
Keeping Your Proof and Filing a Claim
Keep your confirmed booking, boarding passes, the airline's message announcing the diversion or cancellation (SMS or email), and receipts for all expenses incurred. A confirmed booking is a condition for applying the regulation[1], and receipts are what allow you to be reimbursed for necessary, appropriate and reasonable expenses[2].
On site, an airline that cancels a flight or denies boarding must give you a written notice setting out the compensation and assistance rules, as well as the contact details of the designated national body[4]. Ask for it at the counter if it is not offered to you.
Start by filing a claim with the airline. If the dispute persists, you can report it to the DGAC (France's civil aviation authority) in cases of denied boarding, downgrading, cancellation, or delay[5]. For an international flight, you can also contact the European Consumer Centre in your country; for a domestic flight, contact a consumer protection body[3].

Travel Insurance, a Backup Plan, and Staying Reachable
What your travel insurance covers if your flight is diverted or cancelled (accommodation costs, deductibles, any exclusions related to a threat) is not documented by any source in this file. Read your policy before you leave, and ask your insurer to confirm in writing what is covered in that specific situation.
A few general habits, with no figures or sources behind them, that apply to any long-haul trip:
- Keep your documents (bookings, insurance, passport) accessible offline.
- Plan a backup: an alternative booking if possible, or a list of flights that reach your destination.
- Stay reachable: a data plan or backup eSIM, a charged phone, and the airline's and assistance contact details written down separately.
Checklist: What to Do If Your Flight Is Diverted
- Report yourself to the airline as soon as you arrive: if your trip is interrupted, the Your Europe page asks you to report it[2].
- Ask for the written notice of your rights and the choice between a refund, a return flight, and re-routing.
- Photograph the airline's message, your boarding passes, and every receipt.
- File a written claim with the airline, then with the DGAC or your national body if the airline does not respond.
- Contact your insurer with your supporting documents.
