Boeing nears final transition from 777-300ER to newer 777X model

Boeing is on the brink of delivering its last older generation passenger 777-300ER as it shifts focus to producing the 777X. There are only five unfulfilled orders for the passenger 777-300ER, all supposedly for Pakistan International Airlines (PIA). However, it's uncertain if these orders will ever materialize, with the final delivery potentially having already occurred to Altavair LP, a leasing company.

In 2012, PIA confirmed a $1.5 billion order for five 777-300ERs to expand its fleet, but these aircraft remain undelivered. The 777-300ER production has significantly slowed, with deliveries dwindling from 76 units in 2015 to single digits in subsequent years. The possible conclusion, as noted by The Air Current and other industry observers, is that Boeing's 777-300ER final delivery happened in 2024.

Altavair, having taken delivery of what might be the final 777-300ER, leases aircraft globally and has been involved in the aircraft's leasing arrangements. The last documented 777-300ER transaction by Altavair involved transferring an ex-China Southern Airlines aircraft to Ethiopian Airlines.
