Canada is losing some U.S. service but gaining capacity in other markets, and Southwest has its eye on three new Mexico routes from Los Angeles.

Low oil prices are taking a toll on energy industry-related traffic into western Canada. United plans to suspend service after June 30 from both San Francisco and Chicago O’Hare to Edmonton, Alberta; it operates daily E175 flights in both markets. In October, however, United plans to increase Edmonton-Denver service from one flight a day to two. Meanwhile, also on June 30, United will end flights from Houston to Montreal and from Chicago O’Hare to London, Ontario.

And Delta has set a July 31 termination date for its twice-daily service to Regina, Saskatchewan from its Minneapolis-St. Paul hub, ending the last service by a U.S. carrier to the provincial capital. But on June 9, Delta will lay on a second daily roundtrip between Seattle and Edmonton. Air Canada, meanwhile, has just launched a major new U.S. route between Salt Lake City and Toronto.

Across the southern border, Southwest Airlines said it plans to apply for government approvals that should open up new vacation destinations for Rapid Rewards members. The airline wants to begin flying from Los Angeles International to the Mexican resort destinations of Cancun, Puerto Vallarta and San Jose del Cabo. Southwest said it expects to win the necessary approvals by late June, and to begin flying the new routes in November.
