The greatest expenses for your London vacation will most likely be airfare and accommodations.  If flying in comfort and style are your main priority, there are many options amongst the airlines for traveling either in first or business class.  If you’re like the rest of us, finding the most affordable seats with the least amount of hassle is probably what you have in mind!   Here are five basics you need to know before you go:

1.  Do your homework.   If you can be flexible with your travel dates, you may be able to save some money immediately.   Since you’re already on the internet, start checking dates above and getting an idea for what your fare will cost.

2.  Peak vacation time is mid-April through mid-October, so you may be able to save money by flying in the off-season.

3.  London’s primary airport is Heathrow (LHR), just 15 miles west of the city center.  While Gatwick Airport (LGW) is twice the distance, south of London, it may afford you some savings on your air travel — but those savings could be easily eaten by ground transportation to and from the airport itself.   Check both, since better deals may be available to Gatwick from your hometown.

4.  Package deals (which include both airfare and hotel) may help you save money on your two biggest expenses.  You can inquire directly with the various airlines, or you can Visit Travelocity for London Deals.

5.  Take advantage of frequent flyer programs.  Even if you don’t have enough points for a full ticket, you may be able to purchase points from the airlines to cover the difference — so you end up with basically a discounted ticket.  Using American Express or airlines’ credit cards will help you earn miles faster on every day purchases, and these can add up over time.
