Bottom of 777 would entail normally 4 transatlantic or Middle East trips per month sometimes 5 if short trips. There is talk of introducing seeded blind lines as on 400, which would enable more junior pilots to bid for one nice trip per month. Otherwise on seeded blind lines you can request certain days or weekends off or certain destinations.
On short haul you would get mixture of single and multi day trips as everyone wants something different. Would again be blind lines, with ability to request same as on 777. Airbus European route network second to none, with nightstops in most destinations.
Hope it helps.
