Eurowings Discover actually wanted to fly between Frankfurt am Main and the casino metropolis Las Vegas from October 2021. Due to the long-term entry restrictions in the United States of America, the route will not be included for the time being.
At the moment, EU citizens can only enter the USA with a few exceptions, because the Travel Ban, which was enacted by the Trump administration, is still in place. Most recently, US President Joe Biden said that this should not be kept until Thanksgiving. The full vaccination against Covid-19 is then likely to be the basic requirement for entry.
Since Eurowings Discover is primarily aimed at private travelers and is therefore active in the leisure segment, the demand for Las Vegas flights is likely to remain within very narrow limits from October 2021. Therefore one had to reschedule and will - at least for the time being - not fly to the casino city. It is emphasized that it is just a matter of postponement, because they basically want to stick to the Las Vegas plans.
The aircraft that has become available will be used on a different route. This will be presented shortly. It is considered likely that the parent company Lufthansa will hand over a route to the subsidiary Eurowings Discover.
