This may or may not apply depending on how you booked your holiday but if you used a budget airline remember to print boarding passes for outgoing and returning flights.
API or Advanced Passenger Information: in an effort to improve security many countries now require airlines to provide passenger details before they travel. For more details check the DirectGov website
The requirements differ from country to country so you may or may not have to complete this, but your airline should tell you in your booking details if you do.
If it is required this usually needs to be completed 24 hours before you fly or you will not be allowed on the plane! So very important to determine if it is required and where to fill this in.
The EHIC card will only cover essential medical care and will not always cover the full cost. It also does not provide any additional insurance against damage or loss of personal belongings or money so you should ideally arrange insurance before you travel.
Before buying it is worth checking if you already have cover through your bank account. Some of the premium accounts that charge a monthly fee provide holiday insurance cover and in some cases for you and your partner.
If you do not already have cover shop around for good deals. Some tour operators will offer insurance with the package and it may be less hassle to do this.
It is also sometimes the case that you will not be allowed to fly if you do not have insurance. If you think you will be travelling more than once a year then it will definitely be worth while getting a year long policy use comparison websites to find the best cover.
Ensure you have received all tickets that are required. This will largely depend on how you booked your holiday but sometimes tickets will be posted out to you.
If you need to check-in on line then you will need to print your outgoing and returning boarding passes, it is often a good idea to print off two copies and keep them separate just in case. If you are responsible for printing your own boarding passes do you have a working printer with ink? Unfortunately something else to buy or find.
If you plan on using your credit or debit card abroad, even if it is just for emergencies, you need to tell your bank you are travelling. Most banks will block your card the minute you try an use it abroad if you haven't notified them.
Getting to and from the airport – Usually a straight forward operation but depending how good the airport transport links are and flight times this can sometimes be an issue.
If you are relying on public transport and taking an early or late flight you can't always count on public transport being available. Usually the airport website is the place to find this information.
If you are getting a taxi, local firms will likely be cheaper and should be booked a bit in advance to make sure you can get one. Getting a taxi from the airport home again will probably be expensive, although if you are tired you may be able to live with the extra cost.
Again it pays to shop around, be wary of 0% commission shops, they may charge no commission but give you a lousy exchange rate.
Before buying your holiday money go online and check the current exchange rate for your currency the BBC website is a good place to look.
You will not likely get this rate anywhere but it gives you a base to work out who has the best deal. Most shops will also buy your foreign currency back at 0% commission but only if you keep your original receipt. One final note you will not be able to exchange any coins, only notes and you will get a poor rate so it is better to spend it on your holiday.
The Government will issue travel advice for certain destination where there are known risks of any kind that may pose a threat. Although this will likely not be an issue for the popular tourist destinations it is worth checking prior to travelling.
Unfortunately air traffic control strikes, natural and political events will happen. So it worth keeping an eye on the news just before you travel in case you need to make any extra plans. Always check the airport departures and news on the day you travel for any updates or issues that may affect your journey.
Email the hotel a few days before you go to make sure they have your booking. You don't want to end up without a place to sleep or finding out that your room has been double booked. It is also a good opportunity to put in any requests, restaurant bookings or last minute questions to the hotel, sometimes they will be quite amenable to room preferences.
