A United flight took off Monday from Houston, for the first time burning jet fuel that was made from algae-based oil. And Alaska Air begins its demonstration flights from Seattle tomorrow (Wednesday, 2 p.m.) – with fuel made from used cooking oil.
Seattle-based Alaska Air Group is consolidating its two airlines under the same brand. Horizon Air's Bombardier Q400 turboprop planes are being repainted with the Alaska Airlines logo. Alaska and Horizon will continue to operate as separate airlines.
