As travellers, sometimes we have to get clever when it comes to finding flight deals. Back in the summer, it was cheaper for me to fly from Chicago to London Stansted, transferring in Dublin (and even getting a hotel for the night!), than it was flying direct from Chicago into Heathrow or Gatwick. One HUGE benefit of flying through Dublin, is that Dublin airport is one of only a handful of airports in the world where you can actually cross the American border while still being in a different country. Here’s my experience of clearing US Immigration in Dublin.
