EU closes airspace with Belarus. Strike planned by Portuguese immigration officers from 31 May to 28 June

Advice. BELARUS. Following the latest incidents, the Belarusian airline Belavia will not be able to fly to the countries of the European Union and the European Council has called on European lines to stop flying to Minsk or overflying its territory. Most of the European airlines are canceling their flights to Minsk and avoiding crossing its airspace.
For these reasons, it is recommended to avoid non-essential trips to Belarus. Spanish citizens who are in Belarus and wish to return to Spain can for the moment return with a stopover in Turkey. More information here 

PORTUGAL. Portuguese border officials and immigration officers will stage a series of walkouts at several of the country’s busiest airports next month. The action will get under way on 31 May and run through to 28 June. If you are traveling during this period, check with your airline whether you will be affected and allow more time to clear border control when entering and exiting Portugal.
Action is planned at Lisbon airport between 5am and 9am from 1-15 June, and between 9am and midday at Faro over the same period.
Further action is planned at Madeira airport on 31 May, 7 June, 14 June, 21 June and 28 June, again between 9am and midday.
