The best Oneworld lounges at Singapore Changi Terminal 1

Going to be in Singapore in few weeks time and looking forward to check out Qatar lounge. In fact I will be checking all of them including Cathay because I have veeeeeery loooooong layover :-)))))

Much better to leave the Changi, store your luggage at Jewel and head into the city to eat, relax and enjoy before returning, showering, eating and onto your next flight. 

I would agree, but that trip was special - I like to say good bye to someone and came to airport much earlier than I need to.

Best airport in the world to have a long layover.  My daughter and I had nearly 24 hours there last year (I am Star Alliance Gold, so it was all in the SQ lounges etc.) but we sure found plenty to entertain ourselves :)

Few months back I was in Singapore and checked all OneWorld lounges including Cathay one. Cathay does not worth the trouble if you departing from T1 - one would be severely disappointed if (s)he visited any Cathay lounge in HKG. Heck, it does not even have a shower! Qantas First is huge restaurant albeit top notch one with very good showers to compliment. Emirathes has excellent view on take off/landing strip and this is about it - shower rooms located in toilets and very poorly appointed. Qatar has excellent dining options for Business pax and good nooks where you can relax or to do some works, but again shower rooms is very weak point. QF Business is OK, but tend to be overcrowded and BA is very quite and tend to be much less populated than other ones.

My personal verdict - if QF First is an option then go there, take shower, eat and go to relax in BA. If you have business class ticket (AFAIK they do not allow any status guests with economy/PE tickets) go to QF or BA for shower and then go to Qatar to eat and relax. IMHO Emirathes would appeal only for aviation geeks with binoculars.

Yes. I am Gold with Qantas and always head to the Emirates lounge. They have Moët while Qantas only have sparkling wine. 

I always go into the Emirates lounge when flying Qantas through Changi. It is much quieter, the food is a little better and they have Moet not just sparkling wine.

I don't believe CX Silver are entitled to lounge access unless they are flying on Cathay Pacific, but you would be best contacting CX MPC to ask them.

None of the Changi T1 Oneworld lounges are open in the morning, but if you are on MH business class there will be a lounge they direct you to, but it'll probably be the SATS Lounge which is pretty crummy.

Yes.

The inferior Marhaba Lounge.

Appropriate status flying Economy with MH will also have access to this lounge.

I didn't see anything worth eating when I visited in August 2032 and just lived on peanut type snacks with beer and some average wine.

No, because you are not flying on Qantas or a oneworld airline. Whilst you bought your ticket through Qantas, in this instance, they were simply a travel agent, selling a flight on another airline.

IMHO QF and especially BA is much better then CX that is quite inferior to marvelous CX lounges in HKG like The Pier. Saying that it is quite a bit of time to travel to T1 and back (bus only, no trains), so if you have enough time then go ahead to QF and BA. Otherwise stay in CX - there is still plenty of foods there though no showers. Another thing to note - you may be not allowed take a bus to T1 by stuff based on your departure time.

Can we go through the security in T1 using Cathay Pacific boarding pass, after checking in at T4 ?

I think so, though it would not give you any advantage because you still need to go to T1 by bus albeit one that out of transit zone. Why not check it and drop your bags at Jevel Earlier Check-In Facility that located in front of T1? Get you boarding pass, visit any lounge and catch a bus to T4. Just check now much time in advance you can check in at Jevel.

is Cathay Pacific still qualify for using Jewel's Early Check in facility after COVID ?

Cathay hasn't resumed early check-in at Jewel, according to the Changi website at https://www.changiairport.com/en/airport-guide/departing/early-checkin-online.html

"Can we go through the security in T1 using Cathay Pacific boarding pass, after checking in at T4 ?" that's a bit of back and forth, do you have bags to check in? If so, I agree with Serg below, look into the T1 Jewel early check-in desks. But can you enter T1 using a boarding pass for T4? I recall some people having issues with this years ago, but then again, most people flying from T4 would be entering Changi at T4 so maybe the immigration border guards aren't familiar with the rules? If I was you I would do more research into this, check the Changi Airport website, if you can't see anything there then try contacting them on Twitter or Facebook.

Looking at CX716's 6pm departure time, and given that the two of you will be restricted to business class lounges, I would honestly just go straight to T4 and enjoy the CX lounge there. It's closer to HKG's The Deck than The Pier but still quite nice, and saves you the time and hassle and potential stress going back and forth between T4 and T1 and T4. If this was me, I would rather spend more time in Singapore or even wandering around the Jewel and then go straight to T4.

BUT, if you have a lot of time on your hands and are travelling light and are keen to try the T1 lounges, well why not? Just get to the airport extra early. The QF business lounge is pretty good actually and has plenty of showers, which is also something missing from the CX lounge, so you might want to have a nice bite to eat at the QF lounge and then grab a shower before making your way to T4. Drop into the BA lounge by all means too, and even consider the Emerald member in your group doing a Qantas first class lounge visit.

Landing T4 at 3:45pm and departing T1 at 10:25pm, excellent, that's plenty of time to visit all the lounges depending on your class of travel or frequent flyer status. Should be fun, but am sure it will be a bit boring by the end of it, there's only so much 'lounging' anybody can handle.

Emirates isn't a OneWorld airline, and Qatar and Emirates aren't partners, so why would they allow an Emirates passenger into a Qatar Lounge irrespective of cabin or status? Qatar Premium Lounge only accepts passengers in First or Business, but from any OneWorld airline, not just those on Qatar Airways flights.

You can't use any of these lounges as 'on arrival' lounges, you can only visit them if you are departing on a flight and that includes being in transit, but with that gap between flights you are not really a 'transit' passenger. And anyway unless you are staying at the Aerotel hotel which is inside T1,  when your flight arrives at 9pm you may as well go straight to your hotel to get as much sleep as you can. If you have a business class flight to Penang leaving 10am then you can go to the QR lounge  for breakfast. BTW, I presume you are flying MH from T2 to KL and then through to Penang? There's no OneWorld airline which flights direct from Singapore to Penang. If you are on Jetstar then that's not OneWorld, you will be able to visit the QF Singapore T1 lounge but the breakfast spread is pretty limited and anyway you will have to catch the shutt;e bus from T1 to T4 because Jetstar uses T4, in which case you may as well have a proper breakfast at your hotel and head straight to T4 to get there around 8.30am.

Inbound SQ First passengers can visit The Private Room on arrival, don't think that applies to business class, but anyway this article is about the OneWorld lounges at Changi.
