Preparing a trip is not just about choosing a destination and booking a flight. Entry requirements for certain countries, air compensation rules, and insurance requirements have significantly evolved in recent years. Overlooking these aspects can sometimes turn a long-awaited stay into a source of avoidable complications.
Carbon emissions and flight booking: what platforms now display
Since October 2022, Google Flights has displayed a CO₂ emissions indicator per flight, allowing users to compare the carbon footprint of each option at the time of booking. This data, detailed in the Google Travel blog, takes into account the type of aircraft, cabin class, and estimated load factor.

Several airlines and travel platforms have followed suit by integrating their own carbon estimates. The differences between two routes to the same destination can be significant, especially when a layover extends the journey. Comparing flights based on this criterion before finalizing a ticket provides concrete information, just like price or duration.
Resources like voyageblog.fr also allow for cross-referencing experiences and practical data about destinations, which helps refine an itinerary before moving to the booking stage.

Compensation for flight delays or cancellations in Europe
Regulation (EC) No 261/2004 governs the rights of air passengers in the European Union. In March 2023, the European Commission published new guidelines on its application (Communication 2023/C 160/01, Official Journal of the EU, 10/05/2023). The central point: airlines can no longer systematically invoke Covid-19 as an extraordinary circumstance to deny compensation.
Specifically, a delay of more than three hours upon arrival or a cancellation without sufficient notice entitles passengers to a flat-rate compensation, unless the airline proves a genuinely extraordinary circumstance (extreme weather conditions, proven security risks). Ground reports vary on this point: some airlines continue to contest claims, and processing times vary significantly from one carrier to another.
What to check before departure
- Keep all receipts (boarding pass, notification of delay or cancellation, receipts for expenses incurred during the wait).
- Check if the flight departs from an EU airport or is operated by a European airline, which is a condition for the regulation to apply.
- File the claim directly with the airline before contacting a national mediation body, as this is often a mandatory step.
Keeping these elements in mind when booking helps avoid discovering one’s rights afterward, when documents are missing.
Travel insurance: a formality that has become an entry requirement in several countries
Travel insurance is no longer just an optional safety net. Several countries require specific medical coverage as a condition of entry or visa issuance. Thailand, for example, mandates minimum medical coverage for certain long-stay visa types (O-A and LTR visas, according to the Thai Ministry of Foreign Affairs, updated in 2023-2024). Dubai strongly recommends health insurance covering the entire stay for all visitors.
These requirements are not limited to distant destinations. Even within the Schengen Area, the European Health Insurance Card only covers public healthcare and according to local rates, which can leave a high out-of-pocket expense in certain countries.
Criteria to compare between contracts
- The ceiling for medical and hospitalization expenses, which varies significantly from one contract to another.
- The coverage for medical repatriation, which is absent from many entry-level plans.
- Exclusions related to sports or adventure activities (diving, high-altitude hiking, motor sports), often mentioned in fine print.
- The possible waiting period and the conditions for reporting in case of a claim.
Reading the exclusions of the contract before subscribing remains the most cost-effective reflex. A cheaper contract that excludes the visited country or the planned activity offers no protection.

Budget and itinerary: prioritize rather than pile up
The temptation to maximize each day of travel often leads to an overloaded itinerary. Rushing between cities or activities reduces the actual time spent discovering each place and increases transportation costs.
A more effective approach is to set a limited number of stops and focus the budget on priority experiences. Two or three well-explored locations leave more room for unexpected events (a local market, a hike spotted on-site, a restaurant recommended by a local) than six rushed stops.
The budget deserves the same prioritization logic. Booking accommodation slightly above the lower range but well-located avoids daily transportation costs that, when added up, often exceed the price difference. Conversely, activities booked on-site regularly cost less than those sold by online intermediaries, especially in destinations where local offerings are abundant.
Comparing activity prices between booking platforms and local providers takes a few minutes and can represent tangible savings over the entire stay.
A successful trip rarely depends on the number of sites checked off a list. It relies on the quality of choices made in advance, the margins left for the unexpected, and administrative preparation that leaves no gray areas regarding the rights and obligations of the traveler.
