The other answer is incorrect. You will not be prevented from boarding the airplane. The TWOV restriction it cites does not apply to you because you qualify for a visa exemption:
Nationals of Albania, Andorra, Argentina, Australia, Bosnia
and Herzegovina, Brunei Darussalam, Canada, Chile, Colombia,
Costa Rica, Dominica, El Salvador, Grenada, Guatemala,
Honduras, Israel, Japan, Kiribati, Korea (Rep.), Malaysia,
Marshall Isl., Mexico, Micronesia (Federated States),
Monaco, Montenegro, New Zealand, Nicaragua, North Macedonia
(Rep.), Palau, Panama, Paraguay, Peru, Samoa, San Marino,
Singapore, Solomon Isl., St. Lucia, St. Vincent and the
Grenadines, Timor-Leste, Tonga, Trinidad and Tobago, Tuvalu,
USA, United Arab Emirates, Uruguay, Vanuatu, Vatican City
(Holy See) and Venezuela for a maximum stay of 90 days. (SEE
NOTE 51200).
NOTE 51200: The maximum stay is granted within 180 days.
