A single reservation covering multiple travelers, commonly ten or more, for flights, hotel rooms, or both, typically negotiated in advance at a discounted rate in exchange for a contractual minimum such as a room block or attrition clause.
A group booking is a single reservation covering multiple travelers, most commonly ten or more, for flights, hotel rooms, or both. Airlines and hotels each set their own minimum, but the ten-traveler threshold is the most widely used cutoff for unlocking group rates and group-specific booking terms.
Hotel group contracts typically include an attrition clause requiring 80% to 90% of the reserved room block to be filled, with a fee owed on the shortfall if the group falls short [1].
Meetings accounted for 58.5% of the $924.53 billion global MICE market in 2025, reflecting how much recurring group travel companies manage each year [2].
Navan defines a group booking as ten or more travelers and offers both a self-serve Team Travel tool and a dedicated Groups and Meetings team that sources and negotiates rates on the customer's behalf.
A room block reserves inventory at a negotiated rate, but it also shifts financial risk onto the booking company if the block does not fill by the cutoff date.
What is a Group Booking?
A group booking is a reservation for multiple travelers, booked together under a single record for flights, hotel rooms, or both. Airlines commonly define a group as ten or more passengers traveling on the same route and dates. Hotels apply a similar threshold, often expressed as a minimum number of rooms rather than people, though the exact cutoff varies by property.
Group bookings matter because they change the terms of the transaction. Instead of paying published rates and booking each traveler separately, a company negotiates a block of inventory in advance. That block usually comes with a lower per-person rate, but also with a contractual minimum the company must fill or pay for anyway.
How Do Airlines and Hotels Define a Group Booking?
The threshold and the terms differ by supplier type, and knowing which rules apply avoids surprises at settlement.
Airlines generally require ten or more passengers on the same flight, route, and date to qualify for a group fare. Group tickets often come with more flexible name-change deadlines than individual fares, since the full traveler list is rarely finalized when the group is first booked.
Hotels set a group threshold based on room count rather than headcount, and it is frequently negotiable. A negotiated group rate sits below the property's rack rate, the undiscounted price the hotel would otherwise charge, in exchange for the company guaranteeing a minimum number of room nights.
Events and conferences frequently combine both: a room block at the host hotel alongside individually ticketed flights, coordinated through a single group booking tool so organizers can track RSVP status and spend in one place.
Room Blocks and Attrition Clauses: What Companies Are Actually Agreeing to
The financial mechanics of a group booking live almost entirely in two contract terms: the room block and the attrition clause. Understanding both prevents an unpleasant surprise on the final invoice.
A room block is the set number of rooms a hotel reserves for a group at a negotiated rate over a specific date range. The hotel takes those rooms off the market for other guests, which is why it asks for a commitment in return.
An attrition clause sets the minimum share of that block the group must actually fill, typically 80% to 90%, before penalties apply [1]. Contracts structure this three ways:
Revenue-based attrition measures a minimum dollar amount, giving the group flexibility to shift room types or dates as long as total spend hits the target.
Cumulative attrition measures total room nights across the full event, so a strong night can offset a weak one.
Per-night attrition measures every single night independently, which is the strictest structure and leaves no room to average a slow night against a busy one.
If a group falls below the threshold, the fee is usually calculated on the hotel's lost profit on the unused rooms, not the full contracted rate, since the property avoids housekeeping and other variable costs on rooms nobody occupies. Companies with a documented history of accurate headcount forecasting are generally better positioned to negotiate a lower threshold or a cumulative structure than a company booking with a property for the first time.
Best Practices for Managing a Corporate Group Booking
Group bookings reward preparation. A few habits separate companies that avoid attrition fees from those that get billed for empty rooms.
Forecast headcount conservatively, then adjust down before the cutoff date. It is far easier to release rooms from a block before the deadline than to argue about an attrition charge afterward. Build in a buffer between your initial estimate and what you actually contract for.
Negotiate the release schedule, not just the room count. A staged release, for example 20% of the block 90 days out and another 15% at 60 days, gives a company room to adjust as registrations come in without breaching the contract.
Track pickup against the block in real time. Waiting until the cutoff date to check how many rooms have been reserved removes any chance to react. A group booking platform that shows live RSVP and spend data lets organizers catch a slow block early enough to fix it.
Compare group pricing against the property's standard rate before signing. A group discount only creates real savings if it beats what the company would otherwise pay booking rooms individually at the average daily rate.
When Should You Book Individually Instead of as a Group?
Group terms are not automatically the better deal, and a few situations call for booking travelers separately even above the standard ten-person threshold.
Uncertain attendance: If final headcount will not be confirmed until close to the trip, the attrition risk on a room block can outweigh the discount. Individual bookings with flexible cancellation terms may cost more per room but carry no penalty for under-filling a commitment that was never made.
Short lead time: Group rates depend on advance notice so a hotel can hold inventory. A trip inside a few weeks of departure often will not qualify for group pricing at all, making individual booking the only realistic option.
Small, geographically scattered groups: A group booking makes sense when travelers share a route or property. A team spread across five different cities meeting at a single conference may get better individual fares than trying to force a single group contract that does not match anyone's actual itinerary.
Group bookings and corporate hotel discounts work best together when a company can commit to real numbers well in advance. When that certainty does not exist, individual booking with strong policy guardrails is often the safer financial choice.

Frequently Asked Questions About Group Booking
Airlines commonly define a group as ten or more passengers traveling on the same flight, route, and date. Hotels set a similar threshold but base it on room count rather than headcount, and the exact cutoff varies by property. Both thresholds are frequently negotiable for larger or repeat customers.
An attrition clause sets the minimum share of a reserved room block a group must actually fill, typically 80% to 90%, before penalties apply. If the group falls short, the fee is usually calculated on the hotel's lost profit on the unused rooms rather than the full contracted rate.
A room block is the set number of rooms a hotel reserves for a group over a specific date range, taking that inventory off the market for other guests. The group rate is the negotiated per-room price attached to that block, which sits below the hotel's standard rack rate in exchange for the group's minimum commitment.
Navan defines a group booking as ten or more travelers and supports it two ways: a self-serve Team Travel tool for smaller or simpler groups, and a dedicated Groups and Meetings team that sources and negotiates rates directly with hotels and airlines for larger or more complex events.
Individual booking often makes more sense when final headcount will not be confirmed until close to the trip, when the trip falls inside a short lead time that will not qualify for group pricing, or when travelers are spread across different cities and routes that do not fit a single group contract.
Forecast headcount conservatively and release unneeded rooms from the block before the contract's cutoff date, negotiate a staged release schedule instead of an all-or-nothing deadline, and track pickup against the block in real time so a slow-filling group can be caught and corrected early.
