How can you get a great rate on tickets from Philadelphia to London?

We've been doing this for years, which means getting that great deal on a London flight is easy-peasy. You can pocket that extra cash for more than just getting from point A to point B with a little know-how.

Which days of the week are cheapest to fly?

With the right attitude and flexibility, you can fly for less. Below are the cheapest days to fly:

  • Tuesday and Wednesday—You know how most stores are not crowded midweek? Same thing here. So, get on while the getting is good.
  • Thursday and Saturday—Get a head start on that Friday crowd. This also works on your return flight. Shorten your vacay by a day and increase your savings.

What's the Saturday night stay rule?

If you stay through the weekend, generally that return ticket to ILG can be cheaper since you'll be leaving earlier in the week. All those business travelers have less elastic schedules, so that means more savings for you. Good thing to tell your boss if you have a business trip -- wink-wink.

Can you save while traveling during the off-peak season?

Shoulder or off-peak seasons are when most vacationers aren't going to certain locations. So when it is cold, most people head off to warmer places like the Caribbean, Mexico, Hawaii, etc., just like the birds (they had it figured out). But in the summer months, you'll find that Europe is really popular. You can usually save on your flight when you avoid flying during the peak seasons.

Airlines change their rates seemingly by the minute. If a price you want pops up, then grab it! There are a lot of other people that are waiting a great price on a flight from Philadelphia to London. You might miss out on your chance to get the flight and the times you like.
