It may also shave a day off your vacation. And last but not least, remember that a cheap ticket may not necessarily mean you'll end up having a cheaper holiday. Discounted air tickets are often fairly inflexible. Once again, read the small print carefully before purchasing your ticket so that you are fully aware of the ticket's restrictions and conditions. Check passport requirements with relevant authorities in the country you will be travelling to.
Most countries require a passport to be valid several months after the planned return date.
Be sure to renew your passport in advance if necessary. Minors travelling alone with their ID cards or passports must also carry with them a note written by their parents that authorizes them to leave the country. Under no circumstances may a minor travelling alone use his or her parent's passport or the passport in which they are listed. The amount you can withdraw on your credit card is often limited to a certain amount per day or week. Check with your bank prior to departure for details.
