Stocks and shares of airlines have been unstable since the start of the coronavirus pandemic, with international travel having been subjected to some of the strictest restrictions across Europe. Earlier this month, Germany lifted some of the tough restrictions placed on visitors from countries such as the UK and Portugal, which resulted in a positive uptick but then quickly nosedived. Airlines such as Lufthansa, Ryanair, and the International Airlines Group all saw gains before the stocks across Europe fell with the pan-European Stoxx 600, London, Paris, and Frankfurt all seeing decreases.
