I like DL on-line access, makes it very easy to check for missing points. Hilton, on the other hand, sucks!
DL hard copies are mailed on average about 1.5 mos after the flight, so they're pretty useless. I have DL FF statements going back to 1984.... Think I should trash them when we move to a new office in 2 weeks? :-)
P.S. I once cajoled a DL (internal MIS) person to print my entire personal file, with flying history going back to 1983, adn all kinds of comments/remarks. Fascinating! I'll keep that.
