The seats in the A330 and especially the A350, however, are on an extremely high level. All A330neo and A350 planes already have the Suite seats installed, which offer maximum privacy.

By now, modern seats have also become the norm at KLM. Its business class is definitely not a bad choice, also thanks to the good service. Like many other airlines, the Boeing 787 always has the newest business class seats installed.

Before Covid-19, Air France still had 4 different business class versions, but now, as the A380 & A340 have left the fleet, only 3 remain. The business class in the A380 was no longer up to today’s standards, unlike the business class that’s installed in the Boeing 787-Dreamliner and Airbus A350, which is modern and comfortable. This business class is now continuously being installed in other Air France planes as well.

Information & Tips for USA

The USA offers many sights, natural wonders and cultural significance. Thanks to numerous airlines offering flights across the Atlantic, it is always pretty inexpensive to get there. Alternatively, you can also cross the Atlantic by boat.

Immigration, ESTA & Visa Requirements

The USA has one of the strictest entry regulations in the world. Most EU citizens, among others, are lucky to be able to participate in the so-called Visa Waiver Program. If you get an electronic entry permit (ESTA)  for approximately €20, you don’t need a visa for entry.

The Best Time to Visit

Due to its sheer size, the perfect time to visit the USA varies greatly from region to region. In winter, Florida is very popular due to the mild temperatures. In the summer the West and East Coasts are flooded by tourists which drives up the prices for hotels and flights and during the Indian Summer in late autumn New England is a very popular destination. The hurricane season between July and September can be dangerous in the Caribbean and the Gulf of Mexico. Florida and the southern states are regularly struck by these tropical storms. Blizzards occur from the East Coast to the Midwest during the winter months and regularly put air traffic and public life on hold.

The US dollar is widely used throughout the world and accepted as a currency in most tourist hotspots worldwide. That being said, carrying cash isn’t necessary in the US, all you need is a credit card! These are very common in the USA and are accepted pretty much everywhere without any issues. If you already have a credit card in your wallet, you should make sure that it does not charge a foreign currency fee if possible. Carrying a few dollars in cash doesn’t hurt though. You might need cash e.g. for the bus ticket if you want to buy it directly from the driver. Most of the time you even have to give exact change.
