This could be very interesting if you manage to find a cheap business flight on TAP that leaves before February 28 and returns before March 31, as these are part of the rules (see below) for the 50% offer.
We found a few flights from Paris to Boston or New York for 806€ after using the promo Codes: “TP50” or “TAP50” or “MEGAPROMO50”
Be quick, not many seats left for that price !!
You may as well book economy tickets with that promo code.
Here an example:
Below a few dates, search with Google Flights and book direct with the airline HERE
Google Flight to Boston, the dates with 1444€
Google Flight to NYC, the dates with 14XX€
The promotional code is only valid for bookings made online at flytap.com between February 8 – 10, 2019.
This offer is valid for TAP journeys starting until February 28 and completed before March 31.
