Each to their own. Not sure where you plucked $50 for international lounge access equivalent to Qantas First Lounge which you get as a platinum member with Qantas, even when flying Jetstar in Y.I reckon if I was saving $1000 flying VA versus QF 737 to Bali, I'd be delighted with the overall experience including the $50 I spent on getting sloshed in a paid lounge.
Last time I checked Virgin still charge $65 for their domestic lounges for a "casual pass".
