Hi ng78,
As far as I can judge, the Portugese market (and the financial state of the country itself) is still not looking to bright for the moment. But did you consider applying for the 2 big European LCC’s? Easyjet will open a Lisbon base in the very near future and Ryanair already has bases in Porto and Faro and (for what it’s worth) there are rumours already for a long time about a base to be opened in Lisbon as well.
Not really the TAP T&C’s you’re after, but if you really want to go to Portugal this might be your way in!
Boa sorte
