An Post has warned anyone who is waiting for inter-national mail that Covid-19 restrictions will probably mean further delays in the coming weeks.
A spokesperson said international and local Covid restrictions coupled with "limited space for letters and parcels" on far fewer inter- national flights continues to severely affect delivery services.
"As a result, many items posted in Ireland during December for delivery across the world are still in transit," the spokesperson said.
Severe weather conditions in different regions are also affecting services worldwide, An Post added.
The company said it will still be delivering parcels and cards that were sent before Christmas until the end of this month.
"An Post expects to be receiving incoming inter- national Christmas parcels and letters for delivery in Ireland throughout January," the spokesperson added.
The company assured Irish customers it will deliver all items as soon as they are in Ireland.
