It's not the fact that you will be traveling during winter months, which in itself would be a help. But to try and non-rev over the holidays can be a challenge. The D1's will help, as long as your friend is eligible. D2's returning before 3-4 January could do a lot of gate dancing, and D3
's at best can be difficult, and at worst can be embargoed if loads are high enough.
Assume you're out of DFW
, so checked and LGW
flights and a couple of days are running about 70-75% already for that week. Other days are not so bad yet... but it is three months away! FRA
are not as bad yet. If you funnel through ORD
, those can be difficult during holidays. Maybe someone in those stations can give a little perspective from years past.
But if it is possible to slide your dates back a week, you'd sure have an easier time.
Good luck and have a good trip.
