Oh Canada! Yay for your national airline! Air Canada announced today they would remove the second-checked bag fee of $25.

"Although the cost of fuel remains highly volatile and far above historic norms, the recent retreat in oil prices is enabling us to reinstate our previous baggage policy. We are eliminating the second checked bag charge on North American Tango and Tango Plus fares, reflecting our customers' expressed preferences. Further, Air Canada is making its pricing more transparent by removing add-on fuel surcharges for flights within North America and instead adjusting its base fares to cover the total cost of fuel," said Ben Smith, Executive Vice President and Chief Commercial Officer.

Tuesday's Wall Street Journal article (subscription required) "Oil Is Cheaper, But Airline Fees Are Here to Stay," suggested that airlines had long hoped to move to an a la carte pricing system in an effort to increase revenue from passengers and high oil prices gave them the way to do just that.

In stark contrast, United Airlines recently announced the charge to check a second piece of baggage would double to $50 for tickets purchased on or after September 16, 2008.
