Location of Passenger Accommodations

LOPA stands for ‘Location of Passenger Accommodations”, which is a specification drawing of the interior design and layout of the cabin interior.

The LOPA is a diagram displaying the locations of the flight deck, attendant and passenger seats, lavatories, galleys, emergency equipment, windbreakers and other monuments. The Emergency Equipment Listing (EEL) is included as part of the LOPA and lists the part numbers of all emergency equipment.

If an airline wants to change the interior configuration of the cabin in a major way, they must do so through a Supplemental Type Certificate (STC).
The STC will generally cover the following changes:
·       Seating Layout (LOPA)
·       PSU Layout
·       Emergency Equipment Layout
·       Floor path marking system installation
·       Carpet installation
·       Curtin installations
·       Monument installation and removal

For example, the cabin may be reconfigured from a 30C, 150Y to a 180Y configuration.

But what does this mean?

The number preceding the ‘C’ or ‘Y’ code refers to the number of seats. The code refers to the IATA booking code.

The most common codes are listed in the following table:

Booking Code F – full-fare First class,] on airlines which have first class distinct from business class.
Booking Code C – full-fare Business class
Booking Code J – full-fare Premium economy
Booking Code Y – full-fare Economy class
