On our flight itinerary on Delta has my family sitting together. When I bought the tickets I didn't pay extra to choose seats. If they have us assigned together then we should be fine right?!

Sorry, I call BS. I've had seats changed by Delta the last three times I've flown with them... I've NEVER gotten an email about the change. I find out by logging in to their website and checking every so often.If you booked online and gave your email address, you will be notified each time this happens.
I have a flight to DL next month, I've received e-mails about flight changes, the last one yesterday.
I book straight through the airline (no agency). The first time it happened, I made sure my email was correct online. I do get the "it's time to check in" emails. I don't get the change emails, and yes, I do have checked 'notify me for changes'.To PP - sam gordon
Not sure why you seem to not be getting your notifications. It will make a difference who you book with. You have to book directly with the airline for them to send you notifications. If you book thru an agency (which orbitz/expedia would be considered) or other online sources, Delta will notify them of the changes (because they are the booking source) and expect them to let you know as part of their service to you. In my experience, these are the situations when changes go unadvised and you find out when you get to the airport (or check for yourself online).
You just can't depend on any airline notifying you about changes. You need to occasionally check your reservation yourself.
Aircraft changes are the most likely culprit when your seating changes. The computer tries to give you "same type" seating, but if flight is very full, not everyone will be accommodated.
Also, beware if you are traveling with someone, but not booked in the same reservations. When those a/c changes happen the computer will not "know" that you are together, and you could get reseated rows apart. If you booked online and gave your email address, you will be notified each time this happens. You can log into your reservation and try to fix it then.
If all else fails, be very nice to the agent at the gate with you make your request for seating change. They will usually be able to help you out.
oh well, of course. I don't think anyone is disputing that. I check all the time and it looks like Sam Gordon checks. I think we were both commenting on this post:
Notifications don't always happen the way they're supposed to happen. It is up to the user to check and verify. You cannot rely on the airline to do it.
I'm going to back up Sam Gordon here. the notifications I get from Delta are random and sporadic. Last time we flew my husband got the notifications based off his sky miles number even though I had book all the tickets using my email attached to the reservation. Even though my sky miles number was on the reservation I never got a single notice. This current trip, he'll get a notice of time change on a Tuesday, I'll get it (if at all) days later.
Their notification system is screwy.
