I have a Diners Club card primarily for lounge access.
THE LOUNGE LIST IS AT
Airport Lounges - Relax in more than 50 airports around the globe.
The lounges are usually average but better than the Airport transit or gate lounges.
My experiences so far using Diners club Lounges.
Auckland NZ
Basic & comfortable at the far end of the air side concourse. The coffee ,NZ beers & wines were excellent. Snacks & newspapers acceptable
Heathrow.UK
Free lounge is Service Air lounge in Terminal 1 airside which was accessable by shuttle bus from Terminal 3 (Intl to & from Australia) after check in so was USELESS for farwelling non travelling friends or flying to or from Australia & quite inconvenient. Terminal 3 (where most flights to/from Australia originate) has a Service Air lounge but it costs a reduced rate UK Pds 8.50 instead of Pds15 to enter. Every time I have visited in summer the AirCon was broken ,drinks warm and limited snacks (internet access was charged) so not much of a deal or comfort.
Incheon S Korea
Lounge is pleasant with included computer access, alcoholic drinks & nibbles.
Its on land side which means 30 to 45 minutes in arrival Que's + departure lines to access if in transit.
Narita Japan
Lounge is very basic and always crowded when visited. Soft drinks & tea & coffee and no snacks some English reading material. Barely worth the treck to the end of the concourse.
In summary I have always found the Diners lounges only adequate, hard to find and access information inadequate or out of date. Airport staff generally were not aware of its existance .
The Diners club web lounge directory would be much improved if it included printable location maps, directional + timeline advice for arriving, departing and transit passengers.
Example in Stockholm International the out of date directions resulted in a frutless treck across the airport from one side to the other only to find the lounge had been relocated to the opposite side of the terminal.
A lounge existed in St Petersburg but wasnt listed in the lounge booklet of the day and so wasn't utilized.
Re FF Points & Diners Club card
I can also transfer points to Korean air (at a 50% rate) which is useful and have used the points previously (2002) to add to an Westpac Altitude transfer to Air NZ to obtain a FF ticket to Tahiti so I find the FF points transfers suit my travel patterns ( usually to UK once or twice a year) & prefered airline which is Korean Air.
I am currently working towards a Skypass ROW ticket at 140,000 miles for 2007. Since the retail value is about A $3000 it actually values the points at A$0.02 which is a good yield.
I have basically abandoned Star Alliance after a A$1000 excess baggage sting in St Petersberg , Hypoxia ( lack of oxygen- and a suspected precursor to DVT's)) on a Frankfurt to Beijing flight. ( As an Ex RAAF Engineer I have undergone the decompression chamber training and know the symptoms) & the vastly increased points ( and tough class restrictions) for United upgrades to business class from economy across the Pacific & Atlantic.
Recently I transfered 108,000 FF points from Diners on 2 March 06 .
As of todays post (5 1/2 months) despite 3 follow up phone calls nothing has arrived in my Korean Air Skypass account although 5000 inconvenience credit points have arrived in my Diners Club FF account.
A poor and inconvenient customer service result by Diners Club.
I also have 39,000 points on Royal Brunei (Royal Skies) and need 41,000 extra for a UK return ticket which is available at 80,000 points. As the Royal Skies points can be transfered to friends as well as family has anyone out there unneeded Royal skies points they can offer or trade me or vice versa as a longstanding but not quite lost friend.
I hope this post gives some insights for readers as I have recieved much valuable info from other posts for which I do thank the authors thereof.
