Hi Peter C, I would think that it is a bit early for looking for flight only prices for December as they tend to keep most of their capicty for the all in deals until closer to the departure dates. Having said that £890 for a week in Sal for 3 seems like good value. I am no expert this is just my opinion after 2 1/2years of flight watching.
I have just looked at the Thomsonfly website and been quoted £1346 for my wife, daughter & me flight only, from Birmingham to Sal in December. I then looked at Thompson holidays, with hotel on the same dates and got a quote of £890. So, if you are looking to go out to your apartment or villa you may find it cheaper to book a package holiday and just not use the hotel.[?]
