I am still reeling from a very scary situation. I'll keep it brief. Fellow MPers beware. October 2010 I Book 2 J Award Tickets CLT - JFK - LAX - KUL - PVG - JFK - CLT on DL, MH, and MU for 120,000 Miles each. It took about 8 - 10 hours on the phone with Delta and alot of searching and flexibility to do this. The flights are in August/September 2011 June 1, 2011 I am on the Delta website and see there is a schedule change which impacts the flights. I click the "change flights" button and select the impacted leg, and search around for other potential routes home. After clicking through and back a few screens, I get some sort of error message and am directed back to the first screen. When I click on "My Itineraries" - POOF - both award tickets are gone! I call the Delta # immediately and ask them to look up my reservation. Delta says it has been cancelled on-line! I tell them this cannot be so and it should be reinstated. They say that some of the flights are no longer available (namely the LAX - KUL on MH) and that they are willing to redeposit the miles with no redeposit fee. I told them that response was unacceptable! It was a Delta website glitch and now my itinerary is gone. However, I have received no cancellation e-mail, confirmation, or redeposit of the miles. They call back Malaysian and find my ticket and are now working on reinstating those flights. All the other flights have been reinstated. They told me they will call me Friday (June 3) with a response if Malaysian is able to re-obtain our seats (they say they are oversold). So everyone hope for the best that they can get these flights back! Also, be careful when using the change flights option on an award ticket that has been modified. There are glitches which will cause the entire flight to get cancelled.
