I found that Air Mekong is flying the Phu Quoc - Hanoi route. (Vietnam Airlines too, but the exact date there are nő flight, so the only option that I would take is Air Mekong.)
But I need the ticket for April, and the last date that is bookable now is 28Feb. Is Air Mekong always so lazy putting tickets on sale or will they close this route? What do you think, when will be the April tickets shown on the web?
Thanks for the answers!
