Looking at my upcoming flight info for my trip from IAD - DUR with a connection of FRA - JNB. Notice the flight times.

Depart:
10:15 p.m.
Sun., Apr. 1, 2012
Frankfurt, Germany (FRA)

Arrive:
8:45 a.m. +1 Day
Mon., Apr. 2, 2012
Johannesburg ZA (JNB)
Flight Time:
17 hr 30 mn

Return flight

Depart:
6:55 p.m.
Thu., Apr. 5, 2012
Johannesburg ZA (JNB)

Arrive:
5:35 a.m. +1 Day
Fri., Apr. 6, 2012
Frankfurt, Germany (FRA)
Flight Time:
3 hr 40 mn

I know this is nothing compared to lost segments or upgrades and all the other failures we have encountered since March 3. Just wish that that flight from JNB to FRA was truly 3 hours and 40 minutes, that would be wonderful.
