I’m in the UK and today I received a card from the Netherlands that took 39 days to arrive. It seems an insanely long amount of time, even allowing for the pandemic. I also have a card still travelling to Ireland after 2 weeks. Back in the 90s, first-class post to Ireland took 1 or 2 days!
I sometimes wonder if postcards get shoved to the side in sorting offices during busy times and bagged up whenever someone has the time to deal with them. Yet I’m paying the same price as I would for a letter. I can’t see businesses tolerating a situation where air mail takes several weeks to reach a neighbouring country.
