overall very good; just found a bit poor the food options in Narita airport but the in the flight it was good but limited (no real choice to avoid seafood or clearly stay away from pork..); most of the food was tasty tho and the choice was nice, specially their snacks and dessert and drinks. The in-flight systems was so-so (too complicated interface; they should rehaul with a proper UIX), and I specially appreciated their segments of videos capsules about the behind the scenes including an overview of technicalities of their aircraft and days in the life of their pilots. It was refreshing and give a good ideas of the efforts and challenges every employees has to deal with. Loved it!

FAQs about flying to United Kingdom

United Kingdom insider information

  • The UK has a proud theatre tradition. London’s West End is the largest theatre district in the world. The reconstructed Shakespeare’s Globe on London’s Bankside has exhibits, educational programmes, and, of course, an annual season that runs from May to October. In Shakespeare’s Day, the cheap areas of the theatre were filled by “groundlings”, theatre-goers who had paid one penny to watch the performance. These tickets now cost £5. Outside London, the Minack Theatre, an open-air theatre in Cornwall is celebrating its 75th anniversary season with a performance of The Tempest, the play for which the theatre was created.
  • Follow the Ridgeway National Trail from Avebury, a stone circle about 5,000 years older than Stonehenge. Unlike Stonehenge, you can wander among the stones. Close to Avebury are the white horses – five large white horses – cut into the chalk downs. The Cerne Giant, in Dorset, is another giant chalk figure. Beside the sea in Cornwall is Tintagel Castle, said to be King Arthur’s birthplace.
  • Get a glimpse of the Royal Family (maybe) by visiting Buckingham Palace or Windsor Castle, two of the Queen’s official residences. You may spy them at Balmoral in Scotland during the summer months, going to service at Crathie Parish Church on Sunday morning or at the Highland Games in Braemar every September.
  • London is an expensive city, but culture vultures can enjoy museums and galleries free of charge. These include the National Gallery, Royal Academy, Tate Britain and Tate Modern, the Imperial War Museum, and the Victoria and Albert Museum. Outside London there are The National Football Museum in Preston; The Baltic Centre for Contemporary Art in Gateshead and the national museums of Scotland and Wales to name just a few.
  • Among the top seaside resorts are Whitby, Yorkshire; Wells-next-the-Sea, Norfolk; Frinton-on-Sea, Essex; Swanage, Dorset; and Sidmouth, Devon.
  • What is the climate like in United Kingdom?

    The United Kingdom has a generally mild climate. Wales gets most of the rain and Scotland and northern England get most snow in the winter. The south gets most of the mild, dry weather and the vast majority of sunny days.

  • When is the best time to fly to United Kingdom?

    Peak season: The UK is a year-round destination and flights to the UK are always packed with travellers eager to explore the country’s main attractions. Peak summer months are busiest, especially in London, and the major tourist centres. Summer (June to August) temperatures range between 14 and 30 degrees Celsius. Off season: Winter months (December to early March) can be cold (average temperatures about one-two degrees Celsius), but in general, the further north you go, the colder the weather. This is the time to visit for winter sports. Scotland has five main areas for winter sports: Nevis Range, Glencoe, Glenshee, Cairngorm and the Lecht. Shoulder season: Spring (March to May) and Autumn (September to November) can be great times to visit. The tourist season is just gearing up (or gearing down) and the weather can be sunny and warm. May and September, in particular, can enjoy very good weather.

  • What is the best way to travel around United Kingdom?

ScotAirways connects Scottish cities and Eastern Airways links the east of the UK with Scotland. Train service is decent, if expensive. In London, the underground rail is punctual and comprehensive. Buy an Oyster card at any Tube station to get around more cheaply.

There are trams in several cities including Manchester and Sheffield. Croydon has a Tramlink and Blackpool, the resort town in Lancashire, has the UK’s only remaining “traditional” tramway. The National Express bus service is an economical way to get around the UK and it offers a very good service. London buses are fast and regular, linking up the capital day and night. There are good bus services in other cities around England, Scotland, Wales and Northern Ireland. The Postbus is a nationwide service of more than 200 routes, mostly in remote areas. Car hire is easy. All the major companies are represented at airports and in cities around the UK.
