This number has called my cell phone several times, and because I don't recognize the number I don't answer. A message has never been left...it's quite annoying

It's Delta Airlines.  You've probably had a change to a ticket and they're calling to tell you about it. At least that's what my call was about.

Returned call and found it was Delta trying to advise of a change to my plans. ONLY I RECIEVED THE NOTICE from Expedia 2 months ago. They could not explain why I got the call now! Very pleasant about it tho, apoligized for distrubing me

It is Delta notifying me of a change in my flight status.  I called the number back, gave them my confirmation number and they provided me with the updated flight information.

options for being notified

Well after reading all the messages, I call back, it is Delta Airlines. And it was for a flight change. Except that it is bad technology and no message or nobody on the phone when the call comes from them!!! Call back and they will fix the problem for you!!!
No mention about the changes in your next flight and the same number calling again though!!!!

Same here.
Never talks, never leaves messages!!!

Calls leaving no message. This call is from Delta Airlines usually reporting a schedule change to an upcoming flight.

calls two times a day and hangs up

This is a schedule change notification call from Delta Airlines.

I have been getting calls from them almost daily. I also have a flight coming up, but it's in 3 months! I really don't want to keep this up for 3 months.

I have received multiple calls from this number sometimes three a day.  I find it very annoying

Caller with Indian accent looking to molest children.

The caller deserves severe punishment!!!!!!!!!!!!!!! - it has wastered so much time of millions of people.

The caller deserves severe punishment!!!!!!!!!!!!!!!

I've received a call from this number for the past two days at the exact same time (9:07 am EST).  I've ignored the calls and no message was left.  After reading this post, it seems like it might be from Delta Airlines, however, I haven't flown Delta in about 6 years and that was before I had my current cell phone number.  I'm not sure how they got my phone number and I am registered on the Federal Do Not Call List! This is getting quite annoying.

Calls several times per day with no message.

Delta Airlines Schedule Change Department. Calling me that my flights and times that has previously scheduled had changed for my Winter vacation.

My cell phone is registered with "Do Not Call" and I received messages from (800) 925-5052 with NO MESSAGE. I do NOT mind receiving a call if someone is on the line or if there is an important message specifically for me. The way this number is set-up now, it's just harassment!

800-926-5052 IS definitely a number from DELTA AIRLINES.  If you call back, they will eventually pickup, but you'll only receive a taped message (a very general one).

I received a call on my cell phone which is registered with "Do Not Call" from 1-800-926-5052.  No one was on the line and there was no message.

It's definitely Delta, but it's driving me crazy.  Stupid system has called me five times in the past two days about the same change to my flight.  My profile isn't set to receive call notifications, and I even deleted my phone number from the Delta.com website, but I'm still getting these calls.

Called their customer service to get something done about it, but of course I get an ignorant non-English speaker and nothing was accomplished.

I have no flight coming up.  Why the calls?

Yes, you all, it's definitely without a doubt Delta. Call them back for flight changes..it'll be worth it! They changed my flight and I didn't even know it.

I ignored mutiple calls from this number, but after reading this board I called back--yes, it's just Delta, reporting a slight flight time change. Go ahead and answer it!

calling every 2 hours on my cell phone

I have received phone calls from this number for the last 3 days, sometimes two or three times a day, always in sets of two, 2 minutes apart.  No messages left.  I am also on "Do Not Call" list.  If it's Delta, I would prefer an email about an itinerary change, not these annoying phone calls.

yo this number is from delta airlines. if you had recently bought a plane ticket they are calling you about a change in their schedule. the reason why there is no answer when you answer is because their automated system is messed up.

Called 3 times yesterday and did not leave a message and once today

It's Delta.  they called and left not message.  I called them back and told me of a schedule change.
