I assume you know Dr Green the Australian Doctor; who discovered Celiac disease and is in New York. He saved my aunt though she did not have Celiac disease.
Thanks for your report. I flew TAP once from Geneva to Madeira via Barcelona (LX), Lisbon and back via Porto.
The customs guy in Porto wanted to stop us from boarding the plane because at the time US passports in Geneva were not stamped and he insisted we needed an arrival stamp iat the first city of entry.
Also the Barcelona customs guy stamped our passports September instead of August (he must have been on drugs) and he asked us why?
His boss was fortunately at lunch break and we asked him to let us leave as our plane was leaving.
