This question already has an answer here:
I was playing around with Flightradar24 today and noticed three large planes leaving from Frankfurt, Germany, to Seoul Incheon within a few minutes of each other:
- OZ 542, 17:35, Airbus A380
- KE 530, 17:35, Boeing 777
- LH 712, 17:40, Boeing 747-8
All large-capacity aircraft, all from different companies, all departing Germany in the late afternoon to arrive at Seoul at noon tomorrow.
Just out of curiosity: why would airlines choose such a timing? Arriving at midday does not look so overly attractive that everyone would need to compete for it. If there is very high demand for the route, why would the airlines choose to compete in that way instead of going for, say, an hour's spacing to catch different connecting flights? What's in it for them, business-wise?
