Winter isn't the hottest time to travel Europe. But there are plenty of advantages to off-peak travel. Many of the northern countries are gorgeous in the winter. You won't be fighting off hoards of tourists at major attractions. And, as exemplified by a new sale from Aer Lingus, you can get flights on the cheap.
The Irish airline is offering round-trip flights to Ireland for $375 right now. (Technically, the sale is promoting round-trip flights for $399, but we're finding them as low as $374.75.) There are also cheap fares to other locations in Europe like Paris and London, but the bulk of the low-cost tickets are for flights to Dublin and Shannon in Ireland.
The off-peak sale runs through October 3 for travel between November 1 and March 31, 2020. Though, the airline will charge for seat selection and checked bags at the saver fare level, where the low-price tickets are available. Your personal item and carry-on bag are free. Nonetheless, sitting by a stranger and packing light are a small price to pay.
