The travel agency didn't remind me that my passport was about to expire, which delayed my trip. Should travel agencies take responsibility?

According to the travel laws and regulations of most countries, travel agencies have the responsibility to ensure that tourists' travel documents (including passports) are valid during travel, and they need to check tourists' travel documents before traveling. If the travel agency doesn't remind you that your passport is about to expire, which causes you to delay your trip, then the travel agency should usually bear part of the responsibility.

Specifically, according to the provisions of the Tourism Contract Law, travel agencies should provide necessary information and tips to tourists before signing travel contracts, including the validity period of travel documents and other related requirements. If the travel agency fails to provide these tips or information, which causes your travel to be delayed or restricted, you have the right to ask the travel agency to bear corresponding responsibilities, including compensating your economic losses and arranging new travel plans.

Of course, before asking the travel agency to take responsibility, you need to communicate with the travel agency and provide relevant evidence as much as possible to prove your claim. If the travel agency admits its fault and is willing to take responsibility, then you can negotiate with the travel agency to reach a compensation agreement. If the travel agency refuses to take responsibility, it can seek legal aid or complain to the relevant regulatory authorities to safeguard its rights and interests.
