I've flown in economy countless of times. The only time that was unbearable was when we caught ME from LCA to SYD via SIN during the July war in 2006 (flight chartered for Aus. DFAT) We had a group that had just arrived by ferry from Beirut and they hadn't had the chance to go to the hotel to freshen up.
