Deal alert: Fall fares to London from Chicago, Philadelphia from $362
You may think it's too soon to start planning your fall travel, but we say it's never too early to save money on airfare. A new deal offers some solid prices to one of our favorite cities: London.
Aer Lingus has a number of flights marked down in this sale. Ireland's flagship carrier is offering steeply discounted round-trip tickets to London's Heathrow Airport (LHR) from Chicago and Philadelphia for travel in September and October of this year. The best prices involve a layover in Dublin, but considering some fares are 50% off normal prices, it's worth it.
As with many of the deals we spotlight here on TPG, these prices are for economy fares. With Aer Lingus, this gets you a free carry-on bag. If you want to check luggage, it will cost you around $55 each way. In other words, people who pack lightly can maximize their savings.

Sample flights
There are lots of options out of Chicago in this sale. We found $362 round-trip economy fares throughout September, like this one from Chicago's O'Hare International Airport (ORD) to LHR. This fare would typically cost around $800.

We found good availability at this price for October travel out of Chicago, too.

There's also a round-trip October itinerary out of Philadelphia International Airport (PHL) for only $385. According to Google Flights, that price is about half off the normal price you'd expect to pay.

The same round-trip route in September is also available for just a few dollars more, at $392. It applies to the same economy tier, with the free carry-on bag.
