Spain's national carrier, Iberia, is set to plunge many travel plans into further chaos, with the announcement that there will be more strikes later this month and in December.

After a two-day strike this week, Iberia will ground flights for three days (from November 30 to December 2) and then for five days (from December 14 to December 18), reports the BBC: Iberia set for more strike action.

Mainly short-haul and medium-haul flights will be affected. The airline is prevented by law from canceling any flights when there is only one per day. Routes with multiple flights will still have at least one running per day. So if you know your flight is going to be canceled, it might be worth calling the airline to see if you can get on another flight that day. You can contact Iberia here: Iberia Contact Details

Spain's high-speed train service, the AVE, continues to go from strength to strength, with the announcement that it is now the most popular means of getting between Madrid and Barcelona, according to The Olive Press.

The achievement is particularly impressive considering this route is one of the most popular in the world. The Olive Press says it is the fifth busiest in the world, though I've seen several conflicting reports on this.

Why has the AVE become so popular? Because it is (usually) cheaper than flying (especially on short notice), always quicker (when taking into account check-in times), more convenient (train stations are more central than airports), affords a better view and is much more environmentally friendly. Need any more reasons?

There are rumors that developers in the Basque Country are planning to open a new branch of the famous Guggenheim museum, to complement the existing one in Bilbao.

Plans are afoot to build a new museum in Guernica, the former capital of the Basque country (and still seen as the cradle of the Basque culture). According to The Art Newspaper, "The concept is to create a modest-sized venue for temporary exhibitions and to commission artists' interventions in the landscape."

Guernica already receives a moderate amount of tourism, due to its painful place in European history as the site of a massive aerial bombardment from Hitler (on behalf of Spain's General Franco). It also has a very good peace museum to commemorate the atrocities. See Pictures from Guernica.

But politicians clearly hope the new museum could have the same effect it had on Bilbao, turning what was always referred to as an 'industrial backwater' into the vibrant center of tourism it is today.

If plans go ahead, would a case be made to return Picasso's famous painting to the town that inspired it? The artist's depiction of the bombing of Guernica is currently housed in the Reina Sofia in Madrid, but the Basques could make a good case for it to be moved.
