Ok, so I've been keeping score in my head and on my blog, but thought I'd start a thread here in an effort to be more efficient.

Routes With Flat-Beds

Domestic 767 Lie-Flat Review

Domestic 757 Lie-Flat Review

Domestic A330 Lie-Flat Review

Domestic 777 Flat-Bed Review

The idea behind this thread is to keep track of dedicated flat-bed international routes and current domestic routes where either the flat-bed or lie-flat seats in Business can be grabbed. Here is a start of which the information was obtained directly from Delta in December.

Please update the domestic lie-flat / flat-bed routes where you know from experience or can confirm an international route to be fully dedicated flat-bed.
