I'm flying Virgin to NY with DH, DS (6), DS (4) and DS (11 months). We've requested a skycot but I've since read they're quite small and also if we take the bulkhead seats the armrests obv won't go up so I'm fearing it'll be harder for the other two to sleep. Without the skycot the 11 month old will be on my lap! Any thoughts/tips/seasoned travellers advice gratefully recieved.
