Generally, the most affordable prices for traveling to Europe can be found during the low season months, such as autumn (September to November) and winter (December to February), excluding the holiday periods. Avoiding the summer months (June to August) can also help you save money.

It is recommended to start searching for flights at least 2 to 3 months in advance. This allows you to have more options and flexibility to find cheaper fares.

Tuesdays and Wednesdays are often considered the best days to find the lowest priced flights. Avoiding weekend flights can also help you save money.

Some popular tools include flight search engines like Google Flights, Skyscanner, and Momondo, as well as hotel booking sites like Booking.com and Airbnb. Mobile apps are also convenient for searching for deals on the go.

Consider using public transport instead of taxis, opting for more affordable accommodations such as hostels or shared rooms, cooking meals instead of eating out all the time, and taking advantage of discount cards for tourist attractions.

Many European cities offer tourist cards that include free entry or discounts to various attractions and public transport. Check in advance to see if your chosen destination offers this type of card.

When booking flights and accommodations at very low prices, check the cancellation and refund policies, read reviews from other travelers about the accommodations, and avoid providing personal information on untrustworthy websites. Make sure you understand all fees and conditions before confirming your booking.
