Justme,

I think you are not reading what I wrote properly.

You stated that Delta do not advise customers of a schedule change in their flight, even if they know that the flight details have changed, until 1 month before departure because before then it would be subject to further change.

I argued that other airlines routinely email customers of changes. It is low cost and can be done automatically. I named airlines who do this. I argued that Delta do not do this for revenue protection reasons. If they wait until a month before departure, the chances of the customer asking for a refund and making alternative arrangements are significantly reduced. I said you were naive to think otherwise.

Now, I have answered your question comprehensively. I would like you to answer mine. Where Delta has the email addresses of their customers, why don't they programme their system to email customers automatically every time a schedule change is made which affects their booking?
