DL does not post T6 gate numbers on any public source because DL does not do check-in anywhere except T5 but they absolutely use T6. here is the flifo on Delta.com for DL 284/NRT-LAX Los Angeles (LAX) Terminal 5 Gate 68B.
see also flight 2442/LAX-TPA for June 4 if you get on delta.com in the next 90 minutes and you will see Los Angeles (LAX) Terminal 5 Gate 68B .
Since the NRT flight was still on the gate at the time as the TPA flight was boarding and they did not use the same gate.
as for share, I know you all love to look at passenger boardings and, once again, they have absolutely no meaning to the share that any carrier has of the local market because it includes connecting passengers. As I have repeatedly noted, DL does not use LAX as a connecting hub any more than necessary in order to focus on the local market. Even its LAX-California flights are focused on the local market - and DL carries higher percentages of the local market than AA and UA. On LAX-SFO for the most recent quarter, DL carries a higher percentage of local traffic than AA OR UA.
Further, revenue share is what matters - unless of course you want to state the influence of Spirit at DFW based on the number of passengers they carry. In reality, NK carries far less valuable revenue so it is meaningless to say that their share is reflective of their influence on the DFW market based on their passenger boardings compared to AA.
At LAX, AA/US' revenue share is 25%, UA's is 23%, and DL's is 19%. WN's share is far lower even though they carry lots of passengers but at much lower average fares.
Airlines are companies that are in the business to generate profits, not to count the number of units produced. Stockholders care about money.
On that basis, DL's revenue at LAX for the local market is far closer to AA and UA's than a lot of people here want to admit. even the Motley Fool article notes passenger boardings and acknowledges that DL is "nipping on the heels" of AA and UA.
So, we can use a valid revenue metric or we can talk about all the passengers that B6 and NK carry and what WN will carry from DAL compared to AA at DFW and say that is representative of their influence in the local market.
again, AA's fans can argue all they want that AA will get first dibs on LAX gates, no one else will be able to grow, etc. but reality will show that AA will not be allowed to dominate an airport in which other carriers are not able to grow.
Did you all not just learn what happened with the AA/US merger?
