The best arrival lounge
 

If you have (very) positive experience at arrival lounge, would you please share? Also would be useful to know who can get into lounge.

My personal experience is that arrival lounges are quite few comparing those to airside and in general are lower qualify. Also, instead of airline lounges, they are owned/managed by third party providers - Priority Pass, SATS, etc.
Said all above, I think the best experience at arrival lounge I had at ZRH. Also, I think the only place (correct me if I am wrong) where one can get access to the lounge by being Star Alliance Gold, instead of flying on C/F.

I've always enjoyed the Emirates lounges in Dubai.

My favourite is the LH FCT. *A Gold will get you nowhere near that (thankfully). No disrespect.

I've only been to the one at LHR T2 that's accessible to PP holders and it seemed decent for the little time I spent there (albeit fairly dark inside compared to some of the other T2 lounges). The United one seems to get good reviews too but only some *A carriers have access.

The CX F/ OWE Arrivals lounge in HKG is a nice place to shower and relax before tackling the craziness of Hong Kong.

How is the TK arrivals lounge?

...when there aren't 15 people in line coming off the redeye TPACs trying to get in.

For Paris, the CDG AirFrance arrivals lounge is a real advantage to shower before going into the city for a meeting (especially since it is rare to be able to check into a hotel early). No other airline has one there.

Only been to one real one (most of the time I prefer to just get on with my day and get to the hotel to freshen up), the VS Revivals Lounge at LHR. Good breakfast, not overly crowded, nice space to change clothes, and it was perfect since we were hopping on the bus to Cambridge so it was going to be a while before getting to the hotel. Sadly missed out on the CX Arrivals lounge last time I was in HKG.

Most of the time in the US, I just use the standard lounge as my arrivals lounge if I need to shower / freshen up after a redeye (e.g., fly SFO - JFK on DL and then just use T4 DL SkyClub).

I like the ZRH loung as well. It is a great arrivals lounge and even has bedrooms. Unfortunately you are wrong though, there is no access for Star Alliance Gold (only for Miles and More) when flying economy.

Agree - it can get overcrowded at times. Also correcting poster before the lounge is not F/OWE exclusive.

I haven't been to the CX arrivals lounge in HKG for a while but if it was not changed since I was there the last time it is a dark dungeon and a dump. It is ok for a quick shower but this is about it. Used it once and never again (arriving early and heading to a meeting, next time I made sure I could go to the hotel first).

I always find it surprising that, despite just how many showers the LHR T5 arrivals lounge has, one still often has to wait for a shower. Still I'm grateful for it!

The PP arrivals lounge in SIN had pretty good food. Far better than the one at BOM, which is probably the least inspiring arrivals lounge I've been to. Both very strict on timing.

The Ibis does rooms by the hour and it's not that expensive. Shame there aren't any other arrivals lounges for sure.

I thought it was fine for both shower and food, but unlike the CX airside Flounges, it's not one I'd want to spend time at the airport especially for.
