It is advised that whoever is planning to travel to and from Belgium to be tolerant of delayed air and rail services after the Brussels attacks.

The Belgian authorities have warned people to be tolerant towards air and rail services as the country has been rocked by serial attacks at the Zaventem airport and the Maelbeek metro station. The security operations being conducted in the nation will also affect the overall transportation status at the moment. Meanwhile, the UK Foreign and Commonwealth Office has also issued a warning specifically for British nationals and alerted them about avoiding crowded places and public transport.

Travellers are expected to follow this public announcement coming from the local authorities who are strictly managing their security controls. The airport in Brussels where the two serial explosions occurred is still closed and the nation has shut down public transport, including the metro stations. The Guardian reported that the European nation has declared a threat level four after the deadly attacks.

Brussels south airport is still open, but the passengers are required to report to the place almost four hours earlier. Eurostar has suspended most of its services while allowing limited service to some destinations to and from Lille Europe.

The Belgian Department of Foreign Affairs has warned people to postpone non-essential trips to and from the nation. The department has stated that security operations are being reinforced at airports, railway stations and borders across France. This, however, would prompt more security checks, which would require travellers to take some extra time in hand for journeys. The department is hopeful that people will follow the advice and will remain patient.

The foreign affairs department has advised the French people travelling via any means of transport to carry identification proof all the time. Germans have also been requested to travel with normal precautions, according to RTE News. The Brussels Airport has released a statement where it promised to refund the tickets of passengers for Lufthansa Group flights for free. The free refund will be available for to and fro tickets bought for Brussels Airlines, Swiss, Germanwings, Lufthansa and Austrian Airlines between Tuesday and March 28.
