I've repeatedly said that I don't agree with the DOT's micro-management of the airline industry through it's new list of proposed rules (My blog posts on the first round of rules
here, and on the new rules
here). But recently, a few things have come across my desk that I think might actually be ripe for DOT rule-making (or at least a little DOT reprimand).

I'll discuss one of those today -- what is being referred to as "Cancel Down". And I'd like to give a shout out to an
Airliners.net message board post by enilria for stimulating this post and providing the schedule details below.
What is a Cancel Down? We've all had the experience where you book a trip well in advance, and sometime before the departure date, you get an e-mail or call from the airline saying your schedule has been changed. Usually, they change the time of your flight and/or give you a new flight number. Generally, this is in response to some schedule rationalization where an airline cancels some flights to combine two with low bookings or adjusts a schedule for some operational issue.We all understand that this happens occasionally, and as long as it doesn't have a major impact on my trip, I usually don't care too much.But let's think about this a little more critically. To an airline, the top two things (loyalty aside) that impact airline choice are 1) Fare and 2) Schedule. When you buy a ticket, you are expecting to fly at the price you paid at the time of your flight. You may have even chosen to pay more for a more convenient schedule (I do that all the time if I'm trying to choreograph flights into my schedule). By using the Cancel Down, the airline can effectively bait and switch me. They get me to buy my ticket for the right price and schedule, and then they change the schedule on me.Notice when you get these messages, they generally don't say "click here for a refund if this doesn't work", they make you call and complain, or get a special exemption for a refund or fee-free fight change if it's a non-refundable ticket. Also, these changes usually occur within a month or two of the flight, meaning the prevailing fare for that route on other airlines might be significantly higher. Essentially -- you are often stuck.Now things happen that make this necessary from time to time, and one can never assume evil motives. An airline should obviously be allowed some latitude to adjust their schedule as necessary when need be. But a ticket purchase is a contract, and even though the Contract of Carriage allows the airline to do this, it's a sheisty move when done en mass.So that begs the question: How often are airlines doing this? If it's happening a lot, it would signify at best a poorly-planned network schedule, and at worst, a conspiracy to improve yield.I've posted the data for US Airways and United and you can see for yourself below. It's not a small number.Below are the routes that had flight schedules reduced in schedule updates on July 1st for flights that were scheduled to operate in September. So that's 2 months advanced notice. Anyone who was booked on those flights (which have been available for booking for months) will now incur a schedule change. How many flights? For September, we've got ~2,850 flights for just US Airways and United alone (mind you this is a small percentage of their 7k+ flights per day, but still large when you think about the number of affected passengers).The problem here is the airline has almost no incentive to NOT do this. It's a way to increase early bookings by offering a more flexible schedule, and then just bailing on those flights later. You've gotten the yield captive, and now you reduce costs by combining flights. Yes, there is a risk they'll lose that revenue, but the closer to departure they do this, the less chance the passenger has to take their business elsewhere.So what can the DOT do about it? For starters, they can track this to assess how big a problem it is and who are the worst offenders. If they judge it is a problem, then perhaps there's a penalty carriers much pay to people affected. At the very least, they should be offered easy refunds and fee-free transfer to any other flight on the same route by the same airline. At the most, perhaps a $100 voucher, or some Frequent Flier bonus. In reality, airlines should do this on their own. They messed up and had to change the schedule, and they should apologize to their customers and offer some mild benefit as a way to keep them happy. It's just good business. But without that, there seems to be little incentive for airlines to do anything. And after all, this has the biggest impact on travelers who book early -- generally not their high value passengers. That makes it even more important for the DOT to help out passengers who are getting hurt by this practice.Now my personal rant: This happened to me in May on a United flight from JFK to SFO. They changed the schedule on me, and didn't bother to tell me. I only noticed when my FlightCaster app synced with TripIt and I saw the time was off. I went to
United.com and saw that the flight time did indeed change. It's funny -- United Easy-Update calls my cell-phone an average of 10x every time I fly to keep me abreast of non-issue flight status updates, but when they change the time of my flight by 90 minutes weeks in advance -- they don't even bother to let me know!I'm not one to mandate DOT intervention in the airline industry. But in light of their needling ways of late, this is at least one way I think they could productively participate in the dialogue. It's pre-meditated anti-consumer activity, not the on-the-fly poor customer service issues that they are focusing on currently.I would never encourage the DOT, but when the dog wants a bone, may as well give him a rawhide bone from the store than let him dig up a dead bird in the backyard and chew it on your kitchen floor, right?
