The airline TAP Portugal is no longer allowing flight bookings at this time and for at least a week between Madeira and Lisbon from 2nd to 5th January 2020.
The information that appears when we try to do a simulation is ‘unavailable’, with only one daily flight available at this time, but for the most expensive fare, ie Executive. It can cost 433 euros and are already the last seats for sale and for only one flight available on day 2 and seven flights on the other days.
On 1st January, the first three TAP flights will still have Economy seats available from 260.09 to 300.09 euros, but if you want to travel at 5:00 am, 8:45 am or 10:05 am.
In the opposite direction, ie from Lisbon to Madeira, on those days, there are flights with prices from 38.12 euros.
Even on January 6, traveling in Economy can cost 300 euros and traveling in Business 391 euros.
