Let’s focus on BA to find out the meaning of theirs.....

Heathrow-based UK flag carrier British Airways operates a large and diverse fleet of around 290 aircraft. As is customary in aviation, each of these bears a unique registration. All start with the letter G, signifying that they are registered in the UK. However, the remaining four letters have various meanings.

There are certain obvious themes, so let's take a closer look at what they mean. Some are relatively easy and don't require much research. The G-'EU** block refers to the European Union, in which BA's narrowbodies do most of their flying.

The registrations given to the Embraer E-Jet family aircraft that fly for BA Cityflyer also have simple meanings. Specifically, their G-LCY* designations feature the IATA code for London City Airport (LCY), where they are based. Similarly, certain jets at London Gatwick-based subsidiary BA Euroflyer feature corresponding G-GAT* registrations.

Certain British Airways registrations also reflect the airlines acquired over the years. For example, ex-BMI aircraft have been known to use the G-MID* block, referring to BMI's former British Midland identity, whilst former British Mediterranean Airways jets feature G-MED*.

In terms of newer aircraft, BA flies both the standard Airbus A320neo and the stretched-fuselage A321neo. The former have G-TTN* registrations. in line with the written spelling of Three Twenty Neo. The latter's registrations are more obvious, with most being G-NEO*.  However, some A321neos have G-TNE* registrations.

Now we’ll look at the widebody registrations. Here they can be more difficult to decipher.

For example, the B777-200ERs with G-YMM* refer to their delivery in 2000, (MM in Roman numerals. Similarly, the G-VII* B777-200ERs have registrations that reference the Roman numeral for 7.

What about designations the larger B777-300ERs? With registrations following the G-STB* pattern, these refer to the aircraft’s stretched design (compared to the B777-200). One notable exception is a 777-200ER registered G-RAES, the initials of the Royal Aeronautical Engineering Society.

Moving on to Airbus widebodies, the A350-1000 registrations are relatively easy to understand. Following the G-XWB* pattern, they refer eXtra Wide Body, how Airbus markets this aircraft. Meanwhile, BA's first A380 was G-XLEA, with the XL an obvious reference to the superjumbo's size. Its other A380s are registered as G-XLEB, and so forth.

How did former aircraft fit into this process? Aircraft types no longer flown also conformed to certain patterns during their time at oneworld. For example, most of its B767-300ERs had G-BNW* registrations, the 3 letters reportedly meaning Brand New Widebody. Similarly, some B747-400s were G-BNLA, B etc, which stood for Brand New Large Aircraft.

British Airways' former Concorde fleet also had special registrations, from G-BOAA to G-BOAG. They were originally ordered by BOAC, later merging with BEA to form BA. Much like its rivals over at Virgin Atlantic, BA certainly puts a lot of thought into its registrations!

And finally….

Emirates – congratulations to Captain James Ward who has now flown every A380 in the fleet, that’s 123. He joined EK around 8 years ago so achieved this as First Officer, Senior First Officer and Captain.

Staying with Emirates, an example of their quest to become more sustainable. Eyeshades from the First Class amenity pack are donated for use by those learning to teach blind people in the UK.
