Further information

While there are issues that seem more than obvious, it is always advisable to take into account when moving from or to the airport, and especially if you go on some public transport.  1- To the airport - It is convenient to go out with a little more anticipation than you would commonly suggest. If you choose a taxi or a private car service, always keep in mind peak transit times, demonstrations, strikes or events that may take more or less the trip to the airport from where you are. It is always good to be informed about what happens in the place where you find yourself.
If you have a shared transfer service, please have a contact Tel in case of any delay on the part of the company. In these cases, a scheduled collection schedule is already in tenter.
If you are using public transport (bus, train), have the schedules (weekends and holidays usually have fewer frequencies), if you have to transfer and also how to board (if you need a card or boarding pass or paying at the moment to the driver or rider). These are details that seem obvious, but it is advisable to know not to have surprises and suffer a delay that could bring complications.
If you rent a car to get to the airport check well, where you must leave the vehicles. In some airports, there is an exclusive parking lot for rental cars.  2 -From the airport- here is a little less stressful as you don't have the pressure to miss the flight. In the worst case you will arrive later to the place where you are going to stay or to the meeting point where you try to arrive. Once you get out of the plane, pick up your suitcase and finish with the required arrival procedures. Then you have to look for the public transport signs or consult the airport staff. It is very useful to inform the timetables of the buses in case you arrive late at night. Not all of them work 24 hours a day. The same goes for taxis. If you have hired a private car service, keep ready the mobile app to contact the driver. Some transport services hired, have a person waiting for you, identified with a sign.
If you rent a car to go from the airport to your final destination, for more peace of mind it is recommended to reserve it earlier. Rental counters are usually available at arrivals hall.
