I was wondering, the publicly announced departure time of a commercial flight, is it the ETOT (estimated takeoff time) or is it the EOBT (estimated off-block time)? Or maybe some other time?

    $\begingroup$ @TomMcW I removed the references to the tickets. Hope it's better now. $\endgroup$ – Stelios Adamantidis Apr 11 '16 at 23:24

The scheduled time is the EOBT. Flights that depart within 15 minutes of it are considered on-time. Standard taxi times for each airport are included in the scheduled flight time.

  • $\begingroup$ Not SOBT? Either way, definitely some form of BLOCK OUT time, rather than TAKE OFF time is what's on the ticket. $\endgroup$ – Ralph J Apr 12 '16 at 13:10

    $\begingroup$ @Ralph J Good point. Surely SOBT. Didn't remember the term at all. Main point still remains: off-block, not take-off. $\endgroup$ – Sami Apr 12 '16 at 13:14
  • $\begingroup$ Nice. That's what I thought as well. It would also be nice to include a source of information for completeness. $\endgroup$ – Stelios Adamantidis Apr 16 '16 at 18:59
  • $\begingroup$ @Stelios My source is my training, can't name the documents :D $\endgroup$ – Sami Apr 16 '16 at 19:09

In this document you will find some of the many timestamps used in CDM. As you can see there, the EOBT is the timestamp displayed in the flight plan.

The time on the ticket usually corresponds to the ETA/ETD which in term should be STOT (scheduled take-off time).

Are you extracting information from a data source or are you just curious?

    $\begingroup$ Welcome to aviation SE. I'm just curious. That part of the answer could have better been a comment on the question. :) $\endgroup$ – Stelios Adamantidis Apr 12 '16 at 10:50
  • $\begingroup$ Answer is wrong. The ticket shows the PUSH time - block out time. How much later than that takeoff will occur is transparent to the passenger. $\endgroup$ – Ralph J Apr 12 '16 at 11:51
  • $\begingroup$ @RalphJ: why is the answer wrong? Source? PUSH is not an offical time stamp $\endgroup$ – mike Apr 12 '16 at 12:51
  • $\begingroup$ I work in the industry. Time on your ticket is the time we're scheduled to push back from the gate, also known as blocking out. We'll take off some time after that, but this time isn't on the ticket or any passenger-facing published schedule. BTW, that document you linked doesn't say anything like what your answer says about T/O time being published on the ticket. $\endgroup$ – Ralph J Apr 12 '16 at 13:02
  • $\begingroup$ If you have a look at eurocontrol.int/lexicon/lexicon/en/index.php/… it states, that this is an airline / handling agent estimate. I also know, that TOBT is a commitment from the airline (no source though). What exactly do you mean, when you say industry? Airline/airport/handling agent? Also usa/eu? There are differences. $\endgroup$ – mike Apr 12 '16 at 16:45
