For a winter vacation from Newark to Porto, a TAP flight on Feb. 23 is the cheapest option, according to Google Flights. This flight is a red-eye option; it takes off from Newark at 12:15 a.m. and arrives in Porto at 11:55 a.m.

To return to Newark, TAP offers two options at the $396 price point: One leaves Porto at 10 a.m. and the other at 4 p.m. Both returning flight options have a layover in Lisbon.

Since Google Flights also aggregates third-party booking options, there can be price discrepancies between Google Flights and the airline’s website. For this particular trip, Google Flights says the fare costs $375, but if you were to book directly with TAP, it would cost slightly more. (Google Flights says TAP is charging $401, but the website says the fare is around $382.)

All of these discounted fares to Portugal apply to basic economy. TAP’s Discount price only allows passengers to bring a carry-on; all other add-ons such as seat selection and checked luggage have additional fees.

For a flight to Porto, seat selection starts at $45, and the most expensive and roomier seats on the aircraft cost $72. As for returning flights, the cheapest available seats cost $14.

Checking your first bag will also cost an additional $80; a second bag will cost another $105. If you’re only bringing one bag, you will end up paying a total of $160 to check it to and from Porto.
