TAP discrepancy: lie-flat or executive?
I am looking to buy a 1-way ticket from Washington DC to Marseilles via Lisbon (IAD-LIS-MRS) for travel on 26 December 2019. Google flights shows a business class ticket for $1,447 and describes it as lie-flat. But when I check SeatGuru, it shows that Airbus A321 used for this flight has only Executive class with 2 x 3 seats.
Who is right, Google flights or SeatGuru?
How likely the price for Christmas travel (OW, Business) to come down from $1,447?
