Trip planning checklist: what to book first, ranked by how fast it sells out

Flights and beds go first, small-group activities next, and a surprising amount can wait until you're there.

Aino publishes this guide and is building a trip planning app of its own, launching in winter 2027. Every other app here is described from its own site and store listings, with prices dated.

Why the order matters

A packing list is the easy part. The harder question comes earlier: which booking do you make first, and which can wait?

The answer depends on what runs out. A flight seat, a hotel room and a place on a husky sled are all limited. A museum ticket or a walk in the woods usually isn't.

Book the scarce things first and the rest of the plan can bend around them.

We use Lapland in winter as the running example, because it shows the problem clearly. The same order works for a city break or a beach week.

1. Check your passport and entry rules

Do this before you pay for anything, because a passport renewal can take longer than the gap before your trip.

For the EU, non-EU visitors need a passport valid for at least three months after the day they plan to leave, and issued within the last ten years (Your Europe). The EU is also preparing ETIAS, a travel authorisation for visa-free visitors. Check its current status on the EU's official travel site before you go, and only apply through a europa.eu address.

2. Book flights about three months out

Google looked at five years of Google Flights data for departures from the US, published in October 2026. For international trips, prices were lowest on average 89 days before departure. For Europe it was about 90 days, and Google's note is that waiting rarely pays off.

Christmas is the exception to watch. For Christmas trips, prices were lowest about 56 days out, within a low range of 33 to 67 days.

The data covers US departures, so treat it as a rough guide if you fly from somewhere else. A price alert on Google Flights or a similar tool tells you when the fare on your route drops, so you don't have to check by hand.

3. Book accommodation the same day as your flights

Your flights and your bed set the dates for everything else, so book them together. If you book the flight and the hotel fills up a week later, you're stuck with dates and nowhere to sleep.

In Lapland, people book early. Foreign leisure visitors in October to December 2025 booked their trip 5.5 months ahead on average, according to the Visit Finland Tourism Monitor. That's earlier than Google's cheapest flight window, so in a busy destination the rooms can be your real deadline.

Booking this early, pick a rate you can cancel. Check where the place is too, since a cabin 20 minutes out of town changes how you'll reach every activity. Our guide to Rovaniemi without a car shows how much that matters.

4. Book limited-place activities next

Anything with a fixed number of places goes next: small-group tours, timed tickets, and anything that runs on dogs, sleds or machines. A husky kennel can only take as many people as it has sleds.

Visit Rovaniemi says that from December to March, many activities in Rovaniemi sell out early, and recommends booking in advance. You're not the only one worried. In research by Arival, 27 to 34% of travellers said they booked experiences ahead because they were afraid places would go.

Put these on day 2 or later, never on the day you land. Flights can be delayed, and you'll be tired. If you want help choosing which ones to fit in, see how to plan activities for a trip.

5. Reserve restaurants for the nights that matter

You don't need a table booked for every night. You do need one for a birthday, an anniversary, or a holiday when half the town is closed.

Christmas in Rovaniemi is a good example. Visit Rovaniemi's Christmas restaurant page says it's "highly recommended to book a table well in advance." On its list, seven restaurants serve only their own hotel guests on 24 December.

For ordinary nights, book once you're there and know where you'll be at dinner time.

6. Buy travel insurance the day you book

The UK government's foreign travel checklist says to get travel insurance as soon as you book. That way, if something stops you travelling between booking and departure, you're more likely to be covered for the money you've already paid.

The same checklist says to check the policy covers your planned activities, such as adventure sports. For a winter trip, ask about husky and snowmobile safaris before you buy.

7. Leave everything else until the last two weeks

A lot can wait. Worldwide, 12 to 30% of experiences are booked on the day itself, according to Arival.

• Airport transfers: book in the last week or two, once your flight times are final.
• Weather-dependent tours: book on the day. In Lapland that means northern lights tours, after you've checked the cloud forecast.
• Museums, walks and saunas: decide on the day, depending on the weather and how everyone feels.
• Gear: check whether your safaris include thermal overalls and boots before you buy or rent any.

The checklist in one table

Worked example: 3 days in Rovaniemi in mid-December

Say you're planning three days in Rovaniemi in the middle of December. The list plays out like this.

1. July: check everyone's passport dates.
2. July: book flights and accommodation in one sitting, with a refundable room rate. Five months out matches when other Lapland visitors book, and it's well before the 56 day mark for Christmas fares.
3. The same day: buy travel insurance that covers husky and snowmobile safaris.
4. The same week: book the husky safari for day 2 and the snowmobile safari for day 3, timed around the short December daylight.
5. Late November: book the airport transfer once flight times are final, and check what time each safari picks you up.
6. On the trip: book the northern lights tour on the afternoon of the clearest night, and decide on the sauna when you feel like it.

For the full day by day plan, with times and drive minutes, see our 3 day Rovaniemi winter itinerary. For Lapland's specific timings, there's what to book before a Lapland winter trip.

Frequently asked questions

What should you book first for a trip?

Check your passport first, then book flights and accommodation together, since those set your dates. After that, book the activities with a fixed number of places, then restaurants for the nights that matter, and leave flexible plans until you arrive.

How far in advance should you book international flights?

Google Flights found that, on average, prices for international trips from the US were lowest 89 days before departure, based on five years of data. Google's advice for trips abroad is to book as soon as you can.

When should you book activities for a trip?

Book anything with limited places, such as husky safaris or small-group tours, as soon as your flights and accommodation are confirmed. Flexible things like northern lights tours can wait: 12 to 30% of experiences are booked on the day (Arival).

When should you buy travel insurance?

As soon as you book, according to the UK government's foreign travel checklist. The same page says to check the policy covers your planned activities, so ask about things like snowmobiling.

Do you need to book restaurants before a trip?

Only for the nights that matter, like a birthday or Christmas Eve. In Rovaniemi, Visit Rovaniemi recommends booking Christmas tables well in advance, and several restaurants serve only hotel guests on 24 December.
