If I'm reading the material correctly there is a bit of a split between KVS and Expertflyer on DL info - neither seems to have it all. My Expertflyer annual just expired so I'm shopping.

Any word update on:
- DL upgrade info?
- mobile version release date?

As I understand it the split from a DL user is:

KVS
- DL fare buckets
- DL awards
- no DL upgrade info
- web based tool now available but not sure if it supports the above
- no mobile version yet

Expertflyer
- DL fare buckets
- no DL award info
- DL upgrade info
- web based
- mobile version available
