Like most airlines in the world, ANG will find a big difference in their short haul narrowbody and long haul widebody fleets. The Fokker is a PMV with wings and versatile enough to justify being kept on for essential domestic and regional connectivity. The B737 has longer legs and the - 700 could probably replace the B767 on all its current routes. Widebodies are expensive to operate, and will be difficult to fill in the short to medium term. I wouldn't be surprised if the B767s end up being grounded as they will simply be losing money that the airline doesn't have. Once things settle down, any surplus Fokkers could be leased to Alliance for a couple of years until demand picks up again which would be a win/win for both operators.
