Normally deals / hotel prices are much worse for single travellers, but not so with the new Jet2Holidays deal. Use the code "SAVE100" to get £100 off ANY booking.
I've looked at some prices and you can get a 4 day long weekend in Majorca (ex. Manchester) for £180, inc flights, luggage, transfers and hotel. Use the code and it checksout @ £80! Bargain for flights alone, let alone including baggage charges, transfers & hotel!!
The code works for more than 1 person too, but if there are 4 of you travelling, you only save £25per person, instead of £100.
I've booked with some friends and we all booked separately to save the max (and each get our own room, instead of sharing!).
There is also £40 quidco to be had on bookings over £450, so if you are going for a 2 week break, this could be useful!
