Delta the last four trips and Delta going forward.
You will not transport my trophies, you will not transport me.
I have always been happy with Delta.
On another note I always check the tag on my luggage, it pays to make certain it is check through to where you want it.
As a follow up to this post:
In the early part of April I booked a hunt to Zambia flying Delta and Air France. They are airline partners on miles etc.
I recently learned Air France is not flying any trophies. The ticket is non-refundable so there is no changing it. Another airline not to use unless there is no other choice.
