The Triples that are being mainly being retired etc are the -200ER/LR models it seems. -300ER is still the weapon pax and most certainly freight wise.
350/777 was always going to be the future 2030 and beyond and that does not appear to be changing.
Virgin’s debt is so high, a couple hundred mill loss on cheaply sold 777s, you won’t even know. It’s chicken feed. Blame past management and move on.
