Oooh if I had any leave I'd snap this up. £260 is a steal for flights to Mauritius, even though Thomson are absolute rip of agents for their hold luggage which I believe is around £60. You do get a meal though at this price.
At £260 return this price only includes 5kg of hand luggage but if there are two of you you could probably split the cost of 1 case. Either way, it's still cheap and from Manchester direct too. November/December dates.
