Would this be the cause for the delays ?

My friend set off for holiday yesterday, flight was booked for 4.30pm...they're still here in the UK in a hotel 24hrs later, they've not even got on the plane yet. Plane got delayed and then cancelled as there was surprisingly no pilot to fly the plane...they all got placed into a hotel at 1am in the morning, after waiting around in the airport for 9hrs. Flights booked again for 10pm this evening.

Ive just asked her when she booked the flight, she said last saturday which was the 9th, checking the ephemeris, moon was then in its last quarter phase at 22 Aries.

Would it have been this moon phase when they booked the flight, thats caused these delays ?

Ive just found this... Try to avoid taking a holiday during a waning moon as it is a time associated with delays and problems when travelling. from this site https://www.express.co.uk/expressyourself/110687/Let-the-moon-improve-your-life

So even though their holiday is happening in the waxing moon phase, because they booked it during the waning moon phase, this looks to be the astrological reason for the delays.
