Can anyone tell what kind or even which airplane this is?
It may be an A318 with cabine plan like this one for Avianca:



My guesses are:


the emergency light line stops around row 6, with the (red?) curtains around row 4.
the seats arrangement is approximately 3 rows of business class then economy class.
best guess would be 2x3 seats per row, with central screen every three row.
cockpit door is slightly not centered to the left


So it can fit with this type of plane.

Sorry,  I can't guess the company. The curtains seems red, but the cabine does not fit with AirFrance (and Hop) neither British Airways.

EDIT


According to the video posted by @Florian in comments, Avianca is a good guess for the company.
Following the comment of @jean, and considering the shadows on the seats, it may be taken during daylight (in flight or on the ground) but for sure not during night.
