CALGARY — WestJet and Delta Air Lines are one step closer to cementing a transborder joint venture that will expand their codesharing and expand their networks with more frequencies and destinations.

The proposed venture has received clearance under Canada’s Competition Act from the Canadian Competition Bureau (CCB). The CCB issued a no-action letter confirming that it does not intend to challenge the agreement.

“Today’s clearance by the CCB is an important step towards satisfying the conditions necessary to implement the proposed WestJet-Delta transborder joint venture,” said Ed Sims, WestJet President and CEO. “We thank the CCB for its timely and thorough review. The joint venture will lead to more consumer choice, connectivity, and economic benefits on both sides of the border by growing U.S.-Canada business and tourism travel.”

The proposed joint venture between the two airlines is still subject to regulatory approval from the Department of Transportation in the United States.

Upon receipt of all regulatory clearances, the venture will allow the two carriers to deepen their existing partnership with expanded codesharing, reciprocal elite frequent flyer benefits, optimized growth across the U.S.-Canada transborder networks, and co-location at key hubs.

The partners will also begin implementing joint sales and marketing activities.
