Wrong plane - wrong lane!!
I have a large amount of sympathy for the pax on this.
How do you expect people who probably only travel once or twice a year and work in a different industry to know where Bodrum or Arrecife are.
If you turn up at a check in desk and hand over details which say you are booked to Lanzerote, you don't know what the name of the city or airport is Lanzerote. All you know is you are booked to go somewhere warm sunny and fun with your family called Lanzerote.
You expect to be sent to where you are booked. This is part of your contract with the tour operator. You also expect your check-in agent who is dealing with you to be looking at your names or booking to double check it is all correct and that you are indeed on the flight manifest.
Either something went horribly wrong with the booking at the tour operator or travel agency which impacted on manifests or the check-in agent stuffed up. Don't blame the pax.
remember, pax are the people who keep most of us in work!
perhaps check-in staff could pleasently advise their customers (the pax) that instead of have a nice trip, wording like: "please look at your details on the boarding cards I am giving you. They are for you flights to Bodrum in Turkey."
