1. Buy tickets six months before the trip or even earlier
Following this advice, you will receive at least 3 wonderful bonuses: Firstly, you will save a lot. Perhaps several times. Secondly, you will be able to plan your vacation in advance and not leave urgent unfinished business at work. Thirdly, you will live with the idea that somewhere far ahead of you, a journey is guaranteed to be waiting for you. And it always lifts the mood )
2. Do “schengen” for as long as possible
For example, now the Spanish Embassy gives “shengens" for 6 months to everyone without exception. But having gone there once, you will be able to fly to European countries for another six months.
3. Take the penultimate row on the plane
As a rule, the aircraft is filled evenly, starting from the cockpit. Therefore, free seats are usually left in the tail. Ask for seats in the penultimate row and do not hesitate to ask if possible no one else to sit down with you. Whether the latter will turn out or not depends on the fullness of the plane and on your ability to smile.
Why the penultimate one? Because in the last row in most planes, the backs do not recline. In general, if you are lucky, and this happens quite often, you will have several empty seats nearby, where you can, for example, sleep.
4. Rent cars on the spot
As a rule, you cannot book a car of a specific brand via the Internet. Only the class. Book a Mini Cooper, and in the end you get an Audi A3. Well, yes, the class is about the same, but it's a shame, damn it. There are several representative offices of rental companies at any airport. One of them will surely have exactly what you need.
Have a good trip!
