Yesterday we purchased airplane tickets to fly from Luxembourg to London with Luxair.
We would have preferred to fly with British Airways (cheaper rates and safer planes), but due some circumstances our only choice was Luxair.
Anyway, even if we had to fly Luxiar, we did not purchase the ticket from www.luxair.lu, due to their incredible high service fees, when compared to the competition.
Bear with us for a short comparison for service fees:
www.luxair.lu - EUR 20
www.expedia.fr - EUR 0 (yes, zero)
www.lastminute.com - EUR 0 (zero)
www.ebookers.com - EUR 0 (NIL)
To conclude, don't buy directly from Luxair, even if you want to fly with them.
That is if you do not want to throw money out the window.
