Delta's flights from Calgary to Salt Lake City, Utah have dropped throughout their schedule, down to $333 roundtrip after tax.

It looks like United, Air Canada, and Delta flights have dropped down to as low as $319 roundtrip after tax throughout their schedule between now and February 2011.

Delta just dropped a bombshell on their fares to Orlando, Florida throughout the fall and winter, they're showing as $317 roundtrip after tax. That's about 30% less than their nearest competitor in the fall, and a whopping 50% less than anyone else for winter flights.

Delta seems to be showing cheap flights to some places over Christmas that are normally fairly expensive to fly to (at any time of year).

Update: Looks like this is part of a price war between Delta and United for not only flights to Phoenix, but to Charlotte, North Carolina and Philadelphia as well. All 3 cities are available throughout the calendar year, including Christmas, for around $320 roundtrip after tax.

I recently posed this question to Calgarians on the Ycheap.com forums and the response was overwhelming...

Delta has a flight from September 2nd or 3rd to 5th for $276 after tax roundtrip. Yes, that's a Thursday or Friday to Sunday.

Delta has dropped the price of their flights from LAX to Singapore to $600 after tax, roundtrip, for flights near the end of April and into the beginning of May. April 28 to May 12 for example.

It's been a long time since we've seen flights to Australia this cheap. The flights are on Delta, and seem to be available at this price for April and May.
