>Our plane is {departing} in 15 {minutes.}

Departs in 15 minutes.

bednar, czy takie zdanie jest niepoprawne wg twojej wiedzy, The shop is closing in 15 minutes :?

These sentences are vastly different. The closing of a shop can be planned beforehand by a human agent and does not follow a schedule. The departure of a plane, on the other hand, DOES follow a schedule and therefore warrants the use of the simple aspect of the present tense. If somebody said to me "The plane is leaving in 15 minutes" I'd understand it differently. I'd imagine a guy preparing the plane for departure beforehand AND MAKING A CONSCIOUS DECISION that this very plane will make a flight. But that's not how it works, right?

The plane leaves in 15 minutes (= part of an unalterable schedule; a fact)
The plane is leaving in 15 minutes (= an isolated instance; not part of a schedule - a pilot wants to take a plane for a test flight, but he can't as one of the regular planes has broken down and this one will act as a substitute for a flight. The manager tells the pilot that the plane is leaving in 15 minutes. He planned this beforehand)

This is how I see it. I may be a complete nonsense as I am basing the above on my understanding of the two aspects and not on any textbook knowledge :) Do educate me though!

so they went very long /tak mozna napisac?/

bednar, chcialem, abys sobie wyobrazil rozmowe, podobna do tej, w ktorej masz, Our plane is departing in 15 minutes, gdzie nie ma mowy o zmianie czasu wykonania jakiejs czynnosci przez osobe, ktora mowi to zdanie powyzej, jak i te ponizej:
The shop is closing in 15 minutes. W obu przypadkach jest to wypowiedziane przez kogos, kto nie ma wplywu na odlot samolotu czy zamkniecie sklepu. Dla ciebie sa to dwa vastly different zdania. Dla mnie oczywiscie nie.

moze faktycznie ladniej byloby napisac, ... so the ride on the coach to the hotel took a long time.

ale zamknięcie sklepu nie dzieje się codziennie, według harmonogramu. No nic, może ktoś rozstrzygnie?:)

no - fajnie by bylo, jakby ktos jeszcze chcial sie udzielic w tym watku

nie za bardzo lubie...the hotel was very awful

a to co napisal engee30 jest ok.

jest mi bardzo milo to slyszec :)

The present would be favored in this particular example with continuous, however, being by no means impossible.( given a proper context )

There’s another thing. No one being of ‘sound mind’ would use a word ‘depart’ in such situations.
It’s way too formal. You don’t say that when you oversleep and spring from the bed, looking like that shaggy bear after hibernation. But that is the asker’s problem.

what were you actually trying to say, sav :?

I'm saying that 'the present' is better here.
..and agentivity or non-agentivity has little to do with the situation here.

oczywiscie, ze nie ma

tak to mialo byc do bednara , nie dopisalem.
a present naprawde jest ok , slyszalem to niejednokrotnie w podobnych sytuacjach
co nie wylkucza cont znow ze tylko troszeczke z innym odcieniem

I've found in a couple of sources that present simple is better in this case where we speak about schedule.
You can say "The movie starts at 9 pm" and "the plane departs in 15 minutes" as well, in my opinion.

or you can say "our plane is departing (leaving) in 15 minutes (or less)" ... If you want to express that something will be made soon not according to schedule. Maybe I'm wrong but I understand it like this.
