The lounge crawl in SIN is very much up in the air (pun intended). Things are not looking good right now, so I would suggest make sure you have a back up plan for any bookings. At the moment I am flying SYD-SIN with BA a few weeks before, and with QR back to SIN from EU. If it just gets too hard, I will be cancelling.
If the lounge crawl doesn't happen, well, so what!
My original - bookings for this are:
Currently looking at a weekend like:
Fr: MEL-(QF)-SIN,
Sa: SIN-(3k)-BKK,
Su: BKK-(MH)-KUL-(MH)-SIN*, [Crawl]
Mo: SIN-(JL)-HND, HND-(VA)-BNE-(VA)-MEL.
The first two flights in Economy, the rest in Business. The JL flight departs 1:50am (before 6am the next day).
*Complete BKK-SIN business sale fare journey in August.
Fr: MEL-(QF)-SIN, Mo: SIN-(JL)-HND is a QFF award.
Sa: SIN-(3k)-BKK is Starter Max.
Su: BKK-(MH)-KUL-(MH)-SIN* is part of a MH sale I class fare
Mo: ... HND-(VA)-BNE-(VA)-MEL is a Velocity Award.
The first can be cancelled any time for a 6K points charge. The MEL-SIN leg has already been announced cancelled, but it is still showing on GDS (0'ed out) as well as in the PNR.
With the second the only option 3K give in regard to flexibility is to keep rebooking at no fee or get a credit with 6 months validity - but if they reschedule by more than three hours, a full refund.
MH are offering rebooking for fare difference until May 31st.
HND-//-MEL can be cancelled for $60, but I doubt it will operate; two weeks ago, I booked an QF HND-xSYD-MEL as a backup wich can be cancelled for 6K, but I suspect its chances of operating are similar to the VA HND flight.
Accommodation? @SIN 6 hour Aerotel Block is only non flexible, but I have come across good reports of cancellation refunds.
Yes - stuff happens and a lounge crawl becomes rather minor in the scheme of things, so does the prospective 160 SC earn - at this stage my attendance is unlikely.
