Flexible Capacity Management for NHS GP Appointments: Lessons from Airlines and Movie Theaters

 Flexible Capacity Management for NHS GP Appointments: Lessons from Airlines and Movie Theaters

Many industries face the challenge of managing perishable capacity—resources that lose all value if they are not used at a specific time. Airline seats, hotel rooms, and movie tickets are classic examples. Once the flight departs or the movie starts, any unused capacity is permanently lost.

Interestingly, a similar challenge exists in healthcare systems such as the UK NHS GP appointment system. Every day, GP clinics have a fixed number of appointment slots. When a patient fails to attend, that appointment time is permanently lost.

However, unlike airlines or cinemas, GPs do not charge patients directly for appointments, which means traditional price-based solutions cannot be used. Even so, some of the underlying principles of capacity management can still be applied.

The Core Constraint: GP Appointment Slots

In most primary care systems, the real constraint is doctor time.

A typical GP clinic might have:

• A limited number of doctors

• Fixed consultation lengths

• A fixed number of appointment slots per day

This creates a hard limit on how many patients can be seen.

At the same time, demand for GP services is often higher than the available capacity.

The Hidden Problem: No-Shows

A major challenge in healthcare scheduling is patient no-shows.

Patients may miss appointments because they:

• Forget the appointment

• Recover before the visit

• Cannot attend due to work or personal issues

When this happens, the appointment slot becomes unused capacity. Unlike other industries, this time cannot be recovered or reused.

In some NHS clinics, missed appointments represent millions of lost consultation slots every year.

Can Overbooking Work in Healthcare?

Airlines deal with similar uncertainty by using overbooking. They sell slightly more tickets than seats because they know a certain percentage of passengers will not show up.

A similar concept can be cautiously applied in healthcare scheduling.

For example, if historical data shows that 10% of patients miss appointments, clinics might schedule slightly more patients than the theoretical capacity. When done carefully, this can reduce wasted appointment slots while still keeping waiting times manageable.

However, healthcare requires much greater caution because patient care quality must remain the top priority.

Alternatives to Price-Based Flexible Pricing

Since NHS patients do not pay directly for GP visits, traditional dynamic pricing is not possible. However, systems can still introduce forms of flexible access.

Examples include:

1. Priority-based booking

Different appointment types can be prioritized:

• Urgent same-day appointments

• Routine appointments scheduled in advance

• Remote consultations for minor issues

This allows limited GP time to be allocated more efficiently.

2. Time-based release of appointments

Some clinics release appointments at different times:

• Same-day appointments for urgent needs

• Advance booking for planned care

This helps match appointment availability with patient demand patterns.

3. Digital triage systems

Online triage tools can assess patient needs and direct them to:

• GP consultations

• Nurse practitioners

• Pharmacists

• Self-care advice

This ensures GP time is used for patients who need it most.

The Core Principle: Protecting the Constraint

In operational terms, the most valuable resource in primary care is clinician time.

Just as airlines try to maximize the value of each seat, healthcare systems must ensure that every available consultation slot delivers meaningful patient care.

This does not mean treating healthcare like a commercial ticketing system. Instead, it means applying similar capacity management principles:

• Reduce unused capacity (missed appointments)

• Allocate limited resources to the highest-need patients

• Manage uncertainty in demand

A Different Objective

In industries like aviation or entertainment, the goal is maximizing profit.

In healthcare systems such as the NHS, the goal is different:

maximizing patient access and health outcomes with limited clinical capacity.

Even without direct pricing mechanisms, smarter scheduling and demand management can help healthcare systems make better use of their scarce resources.

Flexible Pricing and Overbooking: Maximizing Profit for Perishable Capacity

 Flexible Pricing and Overbooking: Maximizing Profit for Perishable Capacity

Many businesses sell products that expire quickly. Airline seats, movie tickets, hotel rooms, and event seats all share a common characteristic: once the time passes, the product loses all value. An empty airplane seat after takeoff or an unsold movie ticket after the show starts cannot be stored or sold later.

This type of product is called perishable capacity.

From a management perspective, the real challenge is not simply selling everything. The true objective is maximizing profit from limited capacity.

Understanding the Real Constraint

In industries such as airlines, cinemas, hotels, and live events, the main constraint is usually fixed capacity.

• A plane has a fixed number of seats.

• A movie theater has a fixed number of seats per screening.

• A concert venue has a fixed seating capacity.

Because capacity cannot easily change in the short term, the key question becomes:

How can businesses generate the highest profit from each unit of capacity?

This is where flexible pricing and overbooking become powerful strategies.

Flexible Pricing: Selling the Same Seat at Different Prices

Not all customers value the same product equally.

For example, airline passengers often fall into different groups:

• Early planners looking for cheaper tickets

• Leisure travelers with moderate price sensitivity

• Business travelers who may pay much higher prices for last-minute flights

Similarly, movie theaters see different behaviors:

• Discount seekers attending weekday matinees

• Casual viewers choosing weekend showtimes

• Fans willing to pay premium prices on opening night

If a company sets one fixed price, it leaves money on the table.

Flexible pricing solves this by adjusting prices based on time, demand, and customer behavior. Some tickets are sold earlier at lower prices to ensure baseline demand, while other tickets are reserved for customers willing to pay more later.

This allows businesses to capture more value from the same limited capacity.

Why the Best Pricing Sometimes Leaves a Seat Unsold

At first glance, the goal might seem obvious: sell every seat.

However, if every seat always sells out quickly, it often means the price was too low. Demand exceeded capacity, which means customers were willing to pay more.

Optimal pricing usually means demand is very close to capacity, but not always perfectly equal. As a result, sometimes a seat may remain empty. Counterintuitively, this can signal that pricing is close to optimal.

Overbooking: Managing Uncertainty

Another common challenge is no-shows.

Passengers miss flights. Moviegoers change plans. Hotel guests cancel reservations. If businesses sell exactly the number of available seats or rooms, some capacity will inevitably go unused.

To address this, many companies use overbooking.

Overbooking means selling slightly more tickets than available capacity, based on historical data about cancellation or no-show rates. Airlines have long used this approach, but it also appears in other industries such as hotels and event management.

When managed carefully, overbooking helps businesses ensure that their capacity is utilized more effectively while keeping the risk of conflicts manageable.

Applications Beyond Airlines

Flexible pricing and overbooking are not limited to aviation. They are widely used in industries with perishable capacity, including:

• Movie theaters

• Hotels and resorts

• Live concerts and sports events

• Ride-sharing platforms

• Public transportation

These strategies belong to a broader discipline known as revenue management, which focuses on selling the right product, to the right customer, at the right price, at the right time.

The Core Principle

For products with short shelf life, the objective is not simply maximizing sales volume. Instead, the real goal is maximizing profit from limited capacity.

Flexible pricing and overbooking help organizations allocate their scarce capacity to customers who value it most, ensuring that every seat, room, or ticket contributes as much value as possible.
