No communication from Firefly whatsoever. I booked the ticket directly on their website and they have my email address, and also charged me MYR2 at booking to send me SMS updates and nothing there either. It's really criminal, this could really strand someone at an airport with not a lot of options.
I'm deciding now whether to fly Scoot to SIN in the evening, which is several hours later than the Firefly flight, which is not a time I prefer, or a Malindo flight to JHB, which is close to the original time of the Firefly flight.
