Thanks Carlos, I had been reading their page to ensure that Portugália Airlines/TAP Express was appropriate.
Wiki advises - On 14 January 2016, TAP Air Portugal announced that Portugália would be rebranded as TAP Express as of 27 March 2016 as part of the restructuring measures within the group. The division Portugália Airlines however was said to stay independent within the group.
In April 2022, it has been announced that Portugália will be dissolved and fully integrated into TAP Portugal as part of cost cutting and restructuring measures
However as can be seen from the Portugália website the 2022 announcement doesnt seem to have been fully carried out so Portugália Airlines/TAP Express is appropriate
