Hi I was planning to travel to Europe ( Portugal) this summer in June 2021. Turkish Airlines currently offer 30% discount on award ticket . One way DEL- LIS on TK in business class cost 21000 miles n smiles along with taxes ( costing approx 12500/-) . Should I go ahead & book these award tickets. What is advise -wether tourism shall open from India to Portugal in in summer of 2021, keeping in mind Covid Restrictions & also mass Vaccination likely to start in India in early 2021.
