They operate just like any other travel agent, but Asda is only the 'front' name. Asda travel is operated by wefly.co.uk, who are a brand name of P&P associates.
At the end of the day, they are only as good as their suppliers, like all travel agents.

Thanks for reply Sunaddict,was looking for a cheap week away in May, hopefully Majorca as it is a short flight from the North East.Their prices looked good however they use budget airlines and by the time you add in the cost of luggage,transfers etc. the price seems to rocket.

Thanks again
Alan
