Parentheses in Routing
 

Hi, I'm new to these boards and I can't seem to figure something out.

In some routings there are parentheses, such as is in:
BKK-TYO/NGO-HNL(UA/HA)ITO/OGG/LIH/KOA(UA/HA/HA)HNL-SEA-SFO-LAX
-SJC/SNA/BUR/CLD/ONT/SAN-SMF/SAC-SFO

I understand the whole "/" and "-" thing, but what does "(UA/HA)" mean?

More specifically, I'm trying to book SFO-BKK using OZ KLE6M, but I can't seem to get a legal routing using ITA. The routing options are:

BKK(UL)HKG-SEL-LAX(UA)SFO
BKK(UL)HKG-SEL-SFO/SEA-LAX(UA)SFO
BKK(UL)HKG-SEL-LAX(AA)SFO
BKK(UL)HKG-SEL-SFO/SEA-LAX(AA)SFO
BKK(UL)HKG-SEL-LAX(AS)SFO
BKK(UL)HKG-SEL-SFO/SEA-LAX(AS)SFO
BKK(UL)HKG-SEL-SEA(OZ/UA)SFO
BKK(UL)HKG-SEL-LAX/SFO-SEA(OZ/UA/UA)SFO
BKK(UL)HKG-SEL-SEA(AS)SFO
BKK(UL)HKG-SEL-LAX/SFO-SEA(AS)SFO
BKK(UL)HKG-SEL-SFO
BKK(UL)HKG-SEL-LAX/SEA-SFO
BKK(CX)HKG-SEL-LAX(UA)SFO
BKK(CX)HKG-SEL-SFO/SEA-LAX(UA)SFO

BKK(CX)HKG-SEL-SEA(AS)SFO
BKK(CX)HKG-SEL-LAX/SFO-SEA(AS)SFO
BKK(CX)HKG-SEL-SFO
BKK(CX)HKG-SEL-LAX/SEA-SFO

BKK(CI)HKG-SEL-SEA(AS)SFO
BKK(CI)HKG-SEL-LAX/SFO-SEA(AS)SFO
BKK(CI)HKG-SEL-SFO
BKK(CI)HKG-SEL-LAX/SEA-SFO
BKK-SEL-LAX(UA)SFO
BKK-SEL-SFO/SEA-LAX(UA)SFO
BKK-SEL-LAX(AA)SFO
BKK-SEL-SFO/SEA-LAX(AA)SFO
BKK-SEL-LAX(AS)SFO
BKK-SEL-SFO/SEA-LAX(AS)SFO
BKK-SEL-SEA(OZ/UA)SFO

I think if I can figure out the parenthesis thing, I might get a valid routing...

Thanks!

if I had to guess (codeshared by/flown by)

I would think that a carrier between any citypair would mean 'travel must be via' this carrier only (marketing flt no - no operating carrier).

For example, the first one:

BKK(UL)HKG-SEL-LAX(UA)SFO

Means routing is valid if UL is used between BKK-HKG, any carrier between SEL-LAX, and only UA LAX-SFO. Same thing goes if more than one carrier specified.

Ok, thanks.

But, here's a question... what if you go BKK-SEL-SFO and skip HKG and LAX... what are the restrictions on BKK-SEL? UL only, or OZ (the fare airline)? Same question for SEL-SFO. Thanks.

Anyone with useful information? It looks like many of us did not encounter such things at all.

My understanding is a little different. As this is a OZ fare, per default any flight has to be on a OZ-marketed flight within the specific routing, except noted otherwise. In the sample above, this means:

If you choose to route your trip including a segment BKK-HKG, this HAS to be on UL. If you route yourself BKK-SEL directly, you need to fly OZ on that segment. Same story in the end: If you fly SEL-LAX-SFO, the first sector has to be on a OZ-marketed and LAX-SFO on a UA-marketed flight. If you choose to go SEL-SFO directly, you are required to choose an OZ-marketed flight.

Now to the initial question, if you have (UA/LH) in the routing-rules, you can choose between the named carriers using any of their marketed flights on that segment - any reference/restriction in regard to flights "operated by" will be displayed somewhere else in the rules; I think that section is called "flight restrictions". If you can choose any carrier on a given segment, this would be noted as (YY) between the two airports.

Dirk is spot on.
