Of the top 50 inbound country markets, these had the largest year-on-year arrival gains in the period 1 January - 31 May 2018:

• Brazil +30.0% (from a low base related to economy)
• Ireland +17.8% (perhaps related to increased airline connectivity)
• Poland +12.6%

And these had the largest shrinkages:

• Russia -10.5% (probably related to economy, and tensions over US presidential election)
• Finland -5.0%
• Japan -3.7%

Visitation from Venezuela - the only top-50 country impacted by the current Trump travel ban - was up 4.9%.

Also Trump-related: although visitation from mainland China (PRC) was down 1.4%, that from Mexico was up 11.5%.

Looks like all is not lost for US tourism.
