What is ASK and RPK in airline industry?
Available Seat Kilometres (ASK) – a measure of an airline's carrying capacity to generate revenue, taken from multiplying the available seats on any given aircraft by the number of kilometres flown on a given flight. • Revenue Passenger Kilometres (RPK) – a way of calculating the number of kilometres travelled by.
Revenue passenger kilometres (RPK) – also called Passenger kilometres perfromed (PKP): one revenue passenger-kilometre means that one passenger is carried on one kilometre.
RPK – Revenue Passenger Kilometers or revenue passenger miles (RPM) measures the air traffic for airbus and aircrafts using the formula: RPK or RPM = P*D where P is the total of revenue paying passengers and D is the distance travelled in kilometers.
Available Seat Kilometers (ASK) or Available Seat Miles (ASM)* captures the total flight passenger capacity of an airline in kilometers. It is obtained by multiplying the total number of seats available for scheduled passengers and the total number of kilometers in which those seats were flown.
Passenger load factor or sometimes simply called load factor is a measure of an. airline's passenger carrying capacity. It is also known as a measure of efficiency. and hence most commonly used to describe the performance of an airline.
RPK is also known as Revenue Passenger Mile (RPM), which is the most common measure of airline traffic. For example, a flight carrying 140 paid passengers over a distance of 1000 km generates 140 x 1000 = 140,000 RPK of airline traffic. What's Yield in traffic?
In passenger transportation, available seat miles (ASM) or available seat kilometers (ASK) is a measure of passenger carrying capacity. It is equal to the number of seats available multiplied by the number of miles or kilometers traveled by a vehicle.
Revenue passenger kilometers (or revenue passenger miles, in some territories) are a measure of passenger demand in a given market. They are calculated by multiplying the number of revenue-paying passengers aboard an aircraft by the distance the aircraft traveled.
Calculate passenger-kms. = 4,00,000 passenger kilometres per month. Cost per Passenger-km = Total operating cost divided by total Passenger-kms. = 78,75,000/26,25,000 = 33.00.
Revenue passenger miles are calculated by multiplying the number of paying passengers by the distance traveled. For example, an airplane with 100 passengers that flies 250 miles has generated 25,000 RPM.
What is pax capacity?
The most well-known attributed meaning to the term pax is per passenger. So for example, if in a hotel, they have the term pax like this: Buffet at Rs. 400 per pax - This means that the buffet costs Rs. 400 per person.
Cost per available seat mile (CASM) is a common unit of measurement used to compare the efficiency of various airlines. It is obtained by dividing the operating costs of an airline by available seat miles (ASM). Generally, the lower the CASM, the more profitable and efficient the airline.

To get the CASK, direct operational cost is divided by the available seat per kilometre. CASK is essential to determine the airlines cost performance. This is critical to know the airlines capacity to compete and survive the industry.
Load factor is an expression of how much energy was used in a time period, versus how much energy would have been used, if the power had been left on during a period of peak demand. It is a useful indicator for describing the consumption characteristics of electricity over a period of time.
Load factor is a measurement of the efficiency of your household's electrical energy usage. It is calculated by taking the total electricity (kWh) used in the month, divided by your peak demand (kW) multiplied by the number of days in the billing cycle and the total hours in a day.
It's short for Passengers and Passes. In which context, Passengers is short for Paying Passengers. The reason being that from a bus company's point of view it's crucial to distinguish between Passengers (who pay the fare when boarding), and Passes (using a Season Ticket, or some other pre-paid authorisation to travel).
The RPK's leaf sights can be adjusted from 100 to 1 000 meters in 100-meter increments. Range of effective fire is around 800 meters.
Simple Example
The distance between the two airports is 1,190 KM, which means that the RPK per leg flown is 190 (the passenger demand) multiplied 1,190 (the distance traveled by the passengers). Hence, Blank Airlines has 226,100 Revenue Passenger Kilometers per flight leg.
The ask is the price a seller is willing to accept for a security, which is often referred to as the offer price. Along with the price, the ask quote might also stipulate the amount of the security available to be sold at the stated price.
What is the meaning of ask rate?
The term "ask" refers to the lowest price at which a seller will sell the stock. The bid price will almost always be lower than the ask or “offer,” price. The difference between the bid price and the ask price is called the "spread."
In the bid-ask formula, we find out the difference between the price the sellers ask and the price of the buyer's bid. We can see from the bid-ask example of Reliance Industries. For a buy quantity of 47, the bid price is 925.25, whereas the asking price is 925.30. Bid-Ask = 925.30 – 925.25 = 0.05.
RTK = revenue tonne kilometre (one RTK is generated when a metric tonne of revenue load is carried one km).
Key Airline Metrics
Available seat miles is a measure of airline capacity and is calculated by taking the number of seats available and multiplying by the distance flown. Revenue passenger miles is a measure of volume and is calculated by taking the number of passengers and multiplying by miles of flight.
The total cost of transport per commodity is the sum of the cost of transport per mode for the commodity, which in turn is the estimated tonnage transported per mode, multiplied by the mode unit cost in Rand per ton- kilometre, multiplied by the mode average distance transported of each commodity in kilometres.
Passenger car equivalent (PCE) or passenger car unit (PCU) is a metric used in transportation engineering, to assess traffic-flow rate on a highway.
kilometre (km) or kilometer is a metric unit used, outside the US, to measure the length of a journey; the international statute mile (mi) is used in the US; 1 mi = 1.609344 km.
Stage length is the term used to describe the length of the flight from take-off to landing in a single leg. The stage length can directly affect a charter flight cost. This unit of measurement is taken into account when determining an airline or a charter's cost effectiveness.
Key Takeaways
Seat miles are calculated by multiplying the available seats for a given plane by the number of miles that plane will be flying for a given flight.
Revenue passenger kilometers (or revenue passenger miles, in some territories) are a measure of passenger demand in a given market. They are calculated by multiplying the number of revenue-paying passengers aboard an aircraft by the distance the aircraft traveled.
How is RPK revenue seat kilometer calculated explain by giving an example?
Simple Example
The distance between the two airports is 1,190 KM, which means that the RPK per leg flown is 190 (the passenger demand) multiplied 1,190 (the distance traveled by the passengers). Hence, Blank Airlines has 226,100 Revenue Passenger Kilometers per flight leg.
Freight Tonne Kilometres. The equivalent of RPK for freight. One FTK is one metric tonne of revenue load, carried one kilometre. The sum of FTKs for every segment flown by every aircraft over a specific period is the FTK of an airline over that period.
