Easyjet should advice passengers at point of booking that Southend is poorly equipped operationally, to deal with standard UK weather issues and thus if you want a better chance of your flight departing to a long planned, payed for Holiday, taking into account a hotel is fully paid for at destination then you are better to book from London Gatwick, London Stansted or Luton.
Never heard anything so daft in my life. How long would they stay in business if they did. Should they tell Gatwick passengers that Gatwick Airport is more prone to snow so book to travel from Birmingham ?
