Those were the days.

UA still has HKG-SGN, HKG-SIN, NRT-SIN, NRT-BKK

I don't think the US airline industry could handle it if the flood gates were opened, but I would love to see Eighth Freedom rights for QF in the US between JFK and LAX (and rights for UA to sell tickets between SYD-MEL only).

Let's see...

MH used to have LAX-Mexico City
MH: CPT-EZE
MH: LAX-TPE
EK: SYD-AKL supposedly will be bookable on the A380
EK: SIN-CGK
LH: SIN-CGK
Sri Lanka: SIN-KUL
Air Tahiti Nui: LAX-CDG
JL: used to have LAX-GIG
Aerolineas Argentinas: LGW-MAD
TG: used to have LAX-TPE

They already use the A380 on that route.

Couple others:

Back in the 90's, the UA flights within Europe, LHR-CDG, LHR-BRU
JFK-GRU on JL
NGO / NRT - LAX flights on RG, terrible airline.
NRT - Noumea on AF, LAX-PPT on AF.

SCL-EZE is covered by plenty of European carriers, also AC, I think.

So here's another question, LH flies FRA - ADD - SAH, and it's not possible to book ADD - SAH. In the other direction, it's SAH - ADD, and passengers check in at both airports. Is it possible then to fly SAH - ADD, provided that you're (eventually) continuing on to FRA?

I don't see why not?

A few more:

BA have AUH-MCT daily service;
NZ between LHR-LAX daily;
NZ between LHR-HKG (just reducing to 5x week);
KU between LHR-JFK
AI between LHR-NYC
AI used to have LHR-ORD, not sure if they still do;
CX between DXB-BKK
CX between BKK-SIN
JL between KUL-SIN

Moons ago, CX used to have LGW-CDG service on a 747;
United used to have change of guages at LHR onto 727s for flights to Berlin and other points in Germany - all ex-Pan Am routes, of course

Doesn't DL fly AMS-DEL/BOM still?

AC makes a SCL-EZE RT 5 days a week.

Well, that's NW, but I suppose that technically now it's DL. NW does indeed fly AMS-BOM. NRT is also a NW hub and they fly from there to various places in Asia.

Thai Airways fly ICN-HKG and ICN-TPE.
Ethiopian fly CAN-BKK
Sri Lankan and Royal Jordanian fly HKG-BKK.
Not sure if Air India still fly PVG-BKK.
KLM fly KUL-DPS
Air France fly BKK-SGN.

That's incorrect. KL flies KUL-CGK (Jakarta), not DPS.

For a brief period of time, Jet Airways had flights from San Francisco to Shanghai. The flights continued on to Mumbai. They still have flights from Toronto, Newark, and New York (JFK) to Brussels, continuing on to places in India.

When I get some time I'll make up a comprehensive list.

KE fly LAX-GRU.

right - still flying.

Some of them on top of my head. I am trying to avoid all those that are not in service anymore to avoid making it prohibitively long.

CX - TPE - NRT/KIX/FUK/NGO/ICN
TG - HKG - TPE
BR/CI - BKK - LHR (and possibly other European destinations)
SQ - ICN - SFO
VS - HKG - MEL
AI - HKG - KIX

I can't resist this one though. Talking about very long time ago.
CA - HKG - LHR

Yes... I flew it last week. It's a redeye both ways.

SQ fly DXB-DME (for a couple more days, the route will be discontinued on July 6, I believe) and DME-IAH
OM fly SVO-TXL
AF fly BKK-SGN and BKK-HAN
LH fly BKK-SGN
KL fly BKK-TPE
MH fly ARN-EWR
