Last minute charter of aircraft to pick up people, extra costs due to the circumstances, No scratch cards, hire cars, package deals to hide the true cost of the flight so £300 is about right. Decent travel insurance should cover your costs.
Bear in mind that the government is suggesting that carriers don`t fly people there so it would of been a charter
People forget that is cost money to fly aircraft. LOCO`s offset this cost with other items to give you a low ticket price but the costs are still the same its just that its covered by other travel related items.
