Safety Concerns: don't worry these TAP guys are not used to being criticized. You have to understand them: highly paid in a poor country, working for a monopolistic state owned airline that never gave a profit since founded more than 50 years ago.
They believe they are above everyone but time will tell the truth.
You not only offending any TAP personnel, you are offending every single Portuguese citizen. That's not nice to say out loud.
And for the record, since the new Adminstration took place, TAP was done profits. And if you be a interessed person and read some opinion articles in aviation business, you will see that TAP is put as one of the companies that could survive this world crisis.
But leave the Portuguese alone and return to Algarve to enjoy you vacations and make fun you every servant that you encounter....
