Agreed, but by the time you get your denial from EHAS then figure out why it was denied, then try book a test either PCR or Antigen with all the testing sites super busy and then waiting for lab results which are also overwhelmed, then resubmit and wait again for EHAS approval. All during a holiday period, that could be quite stressful. The airlines state that you are responsible for complying with the requirements of your destination, that information is usually found on the official government website not a Facebook post or TTOL post.
