The biggest benefit for me internationally (flying long haul once or twice a month from SIN) is absolutely being able to take a shower between two long-haul flights and, if the lounge is not airside, shave (e.g. The Haven by JetQuay at SIN).<p>Peace and quiet is a second benefit. If you&#x27;re waiting a couple of hours whilst sleep deprived (often the case for business travel or when booking budget flights that leave at 1:30am), those loud, constant announcements are very annoying. Bonus points if the airport has terrible seating and the lounge has comfortable sofas. If you need to work for a bit, it&#x27;s a great place to do so, especially in airports that don&#x27;t have free WiFi (increasingly rare these days).<p>The food is rarely good in Asia (at least at those lounges I have access to). Reheated noodles and some meat if you&#x27;re lucky and flying at the right time. It&#x27;s convenient, at most, saving you the trouble.<p>It really varies by city. HNL and NRT have terrible lounges for PP card holders - basically a room where you can sit for a while, sometimes with a free beer (but there is a great sushi-ya just opposite the NRT lounge). GVA has my favorite ones - nice view on mountains, usually empty (except if Aeroflot is flying soon...) and a decent breakfast with muesli and fresh bread and pastries. SIN lounges often have free massage chairs. Which are available for free in T3 as well, but it saves having to take the monorail there.<p>On timing, if you are flying long haul you can face serious delays (like a huge queue at check-in and security) and need to pad it by a couple hours. Most of the time, you don&#x27;t face these delays and have a spare hour to kill, and in most airports the lounge is a better place to do so. Sort of applies to short haul too; I once missed LHR-GVA check-in on BA by a single minute and they were very annoying about it despite the empty airport (had to book another flight).
