How far in advance should I book a return ticket?

As a general industry pattern, booking 4–8 weeks ahead of departure tends to find better return fares than booking last-minute or very far in advance.

Fare types explained

Most airlines sell several fare tiers on the same flight: Economy (the base fare, often with paid extras like seat selection and baggage), Premium Economy (more legroom, sometimes included baggage), Business (priority boarding, lounge access, flat or angled seating on longer routes), and First Class (offered by a shrinking number of airlines on select long-haul routes). Exact inclusions vary by airline and route — check the fare rules shown at booking.
