If "guaranteed sell" is a thing, it more likely applies to a carrier's guarantee of honoring a sell request that is confirmed by the GDS even if the airline has zero availability in its native reservation system.

I think the answer here is that...hey, you might get lucky, you might not. In theory you shouldn't, but the airfare gods are random and capricious and stranger things have happened.

I would hit the purchase button at DL.com then the OTA. It might work out.

confirming firsthand A1 can yield two A tickets via simultaneous submit for $600 one-way flat beds on HA. you’ll never see more than A1 between LAX OGG towards end of schedule

Another factor to consider is that Yield Management fare allocations are dynamic.
- obviously dynamic in the sense that if a flight is A1, and you buy an A seat, instantly the flight goes to A0.
- but also dynamic in the sense that if that your transaction caused A to hit a threshold, then the flight would be re-analyzed by the YM software. This would be via a 2nd (internally generated) transaction. The 2nd transaction may decide to reset to A1 (or whatever). On the mainframe, that 2nd transaction most likely finished way before your browser had displayed the results of the 1st transaction back to you.
In between your 2 "simultaneous" transactions, the mainframe probably processed (and completed) several hundreds (if not thousands) other transactions.
My experience is with Sabre, which could apply to HA but not DL. However, most airline reservation systems run on a similar mainframe operating platform, so high level concepts are similar.

Hey - if you want to try, go for it.
Remember, if it fails, you have 24 hours to cancel the ticket you may no longer want.

that’s a lot of words that don’t dispute the fact that simultaneous submit works for HA A1 to get more than one seat, from first hand experience this week.
no one who cares about getting the lowest price should accept the naysayers in this thread that it’s not possible.

I wonder if it makes a difference (i.e. helps) if the OTA is selling a bulk/consolidator fare that books into Z, but is an opaque fare.
I'd probably try it with DL.com first, and if the OTA fails you have 24hr to cancel with Delta.

the way it works on HA, despite the know it alls who haven’t tried what i just literally did this week, is that one that one submit tickets normally and the second submit gets a PNR only with no eticket. it takes some extra minutes until the 2nd submit gets ticketed.
literally no one cares about the distinction of simultaneous vs. really really close.
the only relevant data point is that, for HA, if you attempt simultaneous submit, you will achieve your desired goal.
i buy on HA all the time. sometimes just one ticket. and the A1 goes to A0 after one ticket. for days , forever often.

yeah, it is. at HA, there’s obviously an exception process to not reject and instead save the PNR without ticketing in the case where the inventory disappears just after submit. it is this exception process that enables a savvy traveler to sneak an A inventory seat that HA didn’t want to otherwise sell.
