Out of curiosity, how do they handle passengers until the results are out??They were testing all holiday passengers on arrival, without the need to get yourself a PCR test prior to checking in to your flight.
That's were Greek system failed - or I wouldn't say it failed but it causes a lot of problems. The sensible (but difficult to implement) thing is to test everybody and keep passengers quarantined until results are out. But travel agents didn't accept this, not to mention it is not practical to keep all these tourists in quarantine hotels for 1-2 days and then move them.
Hence our government accepted to do sample testing (a "novel" algorithm picks the most suspect passengers based on their background to be tested). These passengers then are let practically free (suggested to self quarantine until results are out). Problem is that quite some positives are not identified by this procedure and/or tourists just run away and hence fresh cases are introduced almost daily to the community. The result is that now we have 300+ daily cases (increasing) while back in July we had less than 10 for several weeks. Hospitals are starting to feel the pressure as ICU beds are getting full.
All these to get probably less than 20% of the tourists compared to other years (and even less revenue because those who come are very "tight").
My wife works in a big-ish 5 star hotel (330 rooms). They opened for August and September only (a normal season runs from Aprir to October) hoping to get Scandinavians who didn't finally make it (their countries didn't allow traveling or imposed 2 weeks quarantine to returning travelers - hence nobody dared to leave). Highest occupancy they achieved was 50ish rooms for a couple of weeks - I am pretty sure their total income is not enough to cover even electricity bills.
Overall only time will show if it worths it - but I highly doubt it.
