I looked back through our records, and I didn't find any trips delayed that much in the last two months. I think what you saw was a special one-day trip we had. Since 9/11 we cut back to one flight per day to HNL, but as the loads picked up, we put a number of extra sections back on the route. Some of them (for crew scheduling reasons) left later in the day - some as late as 8pm. That is probably what you saw.
But in general, yes, the DC-10's are getting a little long in the tooth. It'll be nice not to have to deal with all the little day-to-day problems of a 30 year old jet.
ATA L1011: We used to use the -30's on a regular LAX - Tahiti charter for Renessance cruises - about 8 1/2 hours each way. Unfortunately the cruise line went belly up after 9/11, so we don't do that trip any more. That was our longest regular flight using the -30, but there have been charters using them, including one that went Kona - New Orleans nonstop.
Our DC-10-10's have a capacity of 304, and the new 767's have 252. A little drop in capacity, but management expects to increase frequency on some routes to make up the difference.
P.S. I start 767 training next month. Should be fun!
One smooth landing is skill. Two in a row is luck. Three in a row and someone is lying.
