Definition
The letter code and fare brand behind your ticket price, such as booking class Q or a saver fare. It decides change and cancellation fees, baggage, free seats and frequent-flyer miles, so passengers in the same cabin can hold very different tickets.
Cabin, booking class and fare brand
Three layers decide what you've bought:
- Cabin: economy, premium economy, business or first.
- Booking class: a single letter such as Y, B, M, Q or T that stands for a price bucket. Each flight has a limited number of seats in each bucket.
- Fare brand: the name the airline markets, such as saver, value, classic or flex. It bundles the rules on baggage, seat selection, meals, changes and refunds.
Some Indian airlines also sell cabin-bag-only fares on domestic routes, such as Air India Express's Xpress Lite, which are cheaper because they include no checked bag.
Why fares rise as you watch
When the cheapest bucket sells out, the next booking class opens at a higher price. That's why a Delhi–Goa fare can jump from ₹5,500 to ₹8,000 overnight. It also explains a common family puzzle: if only two seats are left in the cheapest class, a booking for four is priced entirely in the next class up. Booking two and two on separate PNRs can be cheaper, but keep a parent with each child and accept that the bookings are handled separately if plans change.
What to check before you pay
- The cancellation and change fees in the fare rules, not only the headline price.
- Whether checked baggage is included. See baggage allowance.
- Miles earned: deep-discount classes may earn a fraction of the miles, or none.
- If your plans may change, a flex fare can cost less overall than a cheap fare plus a change fee and the fare difference.
