"***************IMPORTANT INFORMATION**************

For those of you who are trying to upload your information into the EHAS system, please note that it is currently down and it is being worked on.

If you're traveling today please proceed to the airport with your negative test result as the airlines have all been informed and they will let you on the flight.

For those travelling tomorrow, please continue to check in on the EHAS site, however if you are still unable to get on, you can show your negative test results to your airline and they will let you board. Further instructions will be given by our Ministry of TEATT"
It's been corrected now but good to know for future issues with EHAS.
