How do I ensure I have the best deal for flight ?? BA LGW to Tampa 13/12-3/1

[knakered]

Anyone know of a way I can ensure that I have the best deal on this...ie special offers - best agency/website...there are 2 adults (3children, 9,7,6) and 1 infant on lap...also need cheapest car hire (seats 6) for the duration

The best web site i use is;
SkyScanner

Check out - The Money Saving Expert;

Martin Lewis

Worth signing up for his weekly news email.

Another 2 i check are;

EBookers
XL

hope this helps

Kayak.com is good for flights - it searches all airlines, so you can check you have the best deal.
