Amadeus DF Command: Basic Math Calculations

A complete guide to the DF command in Amadeus — how to perform basic mathematical calculations directly in the terminal without leaving your workflow.

DF is the Amadeus GDS command used to perform basic mathematical calculations.

Category: Miscellaneous / Calculations.

It allows you to quickly perform calculations directly in the Amadeus terminal. It is a companion to the other calculation tools — for unit and temperature conversions use DK, for time and date calculations use DD, and for currency exchange and money conversions use FQC and the GDS currency conversion commands.

Add two numbers:

DF134.55;22.50

This adds 134.55 and 22.50. The semicolon separates the values to be added. Use it to total multiple amounts — for example a base fare plus a tax, or several service charges in one calculation.

Subtract one number from another:

DF324.56-25.89

This subtracts 25.89 from 324.56. Use it to work out a fare difference, a refund amount, or the net value after a penalty deduction.

Multiply two numbers:

DF152*8

This multiplies 152 by 8. Use it to calculate a group total — for example the cost of a ticket multiplied by the number of passengers.

Divide two numbers:

DF5135/82

This divides 5135 by 82. Use it to split a total between passengers or to work out a per-person share of a group cost.

Perform an exponential calculation:

DF10**2

This calculates 10 squared. Exponential calculations are less common in everyday travel work but useful in technical references, currency calculations, and where a value must be squared or raised to a power.

Calculate 10% of 368:

DF368P10

The P indicates a percentage calculation, and the entry works out 10% of 368. Use it to work out a commission, a discount, a service fee, or a tax that is quoted as a percentage.

Percentage calculations are among the most frequent uses of DF in daily travel work — for example when calculating agency commission on a fare, working out a corporate discount, or quickly confirming a service fee that the airline has quoted as a percentage.

Use DF whenever you need to perform a quick calculation without leaving the Amadeus terminal. Typical scenarios include:

• Adding a base fare and taxes to check a total.
• Working out a fare difference between the old and new ticket.
• Calculating the cost of a booking multiplied by the number of passengers.
• Dividing a group total to find the per-person share.
• Working out agency commission or a corporate discount as a percentage.
• Checking a service fee or tax quoted as a percentage of the fare.
• Confirming figures before entering them in a TST or manual pricing entry.
• Avoiding the need for a separate calculator or spreadsheet during a booking.

A typical session using DF might look like this:

• Retrieve the PNR with RT or continue with the current booking.
• When a calculation is required, enter the appropriate DF entry — for example DF134.55;22.50 to add values, or DF368P10 for a percentage.
• Note the result and use it in the fare, refund, or commission calculation.
• If needed, confirm the currency and conversion with FQC or check the exchange rate with FQA.
• Enter the figure into the TST with TTK or a related TST update command.
• Continue with pricing using FXP or with the ticketing workflow.

• DF → performs basic mathematical calculations: addition, subtraction, multiplication, division, exponents, and percentages.
• DK → converts units, temperatures, and decimal values.
• DD → calculates time differences, local times, and dates.
• FQC → converts currencies and retrieves historical exchange rates.
• FQA → displays IATA Rates of Exchange for a country.
• FQB → displays bankers’ selling and buying rates.
• GDS currency conversion commands → complete guide to money conversion in Amadeus, Sabre, and Galileo.
• GDS calculator guide → an overview of the calculation and conversion tools available in the GDS.

The distinction matters: DF handles arithmetic; DK handles physical units; DD handles time and dates; FQC, FQA, and FQB handle currency and exchange rates. Together they cover every calculation an agent needs during a booking session.

Important: The DF command performs raw arithmetic only. It does not apply fare rules, taxes, currency conversions, or rounding conventions defined by an airline or by IATA — it simply calculates the numbers you enter.

For any figure that will be entered into a ticket or a refund, always confirm the correct fare, tax, and currency treatment with the applicable rules — use FXP for pricing, FQC for currency conversion, and the fare rules for any rounding rules.

What does the DF command do in Amadeus?

DF performs basic mathematical calculations — addition, subtraction, multiplication, division, exponents, and percentages — directly in the Amadeus terminal.

What does DF134.55;22.50 mean?

It adds 134.55 and 22.50. The semicolon is used for addition in the DF entry.

What does DF368P10 mean?

It calculates 10% of 368. The P indicates a percentage calculation.

How do I subtract, multiply, or divide?

Use the corresponding operator in the entry — - for subtraction, * for multiplication, and / for division.

Does DF convert currencies or units?

No. Use FQC for currency conversion and DK for unit conversions.

Can I use DF for fare calculations?

DF only performs raw arithmetic. Fare calculations that involve taxes, currency conversions, or airline rounding rules must be done with the correct pricing commands, such as FXP.
