Just curious, why would they only fly a 737 with so many people stranded there? Ly4 landed there with a 787 so I'm assuming the runway is big enough for those planes
guesses...
Quicker turnaround with less people
crew needed in position
if the runway gets hit while it on the ground in TLV it needs a much shorter runway...
has less people, which is the point - they don't want tons of people on the ground in TLV
Etc...
