Something really screwy with the search/ booking engine: LM's IT can be something else!
Found ADL-SIN-HKG (all J) on April 23 and most nearby days, only to have it disappear 10 mins later, then reappear/ disappear again.
Watched and pounced with CC in hand and booked quickly with confirmation.
People on the LH F thread also noticed sudden appearance/ disappearance.
They should sack the hamsters and use electricity for their computers!!!
