Re-release/re-dispatch has been in use for many years, and requires sufficient fuel for an enroute destination/alternate, with sufficient fuel on board to the continue to destination/approach/divert to alternate/then hold.
This is all nothing new, and I'm surprised that the so-called professionals at EK have never operated accordingly.
In addition, re-release/re-dispatch, if applied properly, absolutely does
not require committing to
any airfield.
Suggest EK management and pilots have a re-think about all this...as SaudiArabian was able to save huge amounts of fuel using the applicable re-release/re-dispatch procedures...circa 1982.
