I am planning to arrive at Houston George Bush Intercontinental Airport (IAH) on Sunday November 28th at 05:20 AM local time, and I have a flight with the same airline (United) that leaves for Las Vegas at 07:30 AM local time. Would that be enough time to get my luggage, clear customs and board the other plane?
Additionally, as pointed out in the comments, my flight is on the Sunday after Thanksgiving, which is typically one of the busiest days of the year for domestic air travel in the US.
I found this question from 2015 and the accepted answer says that with a layover time of 1.5 hours the OP almost certainly has enough time to make the connection (so with 2 hours 10 minutes I should be good), but I'm asking anyway because a lot can change in 6 years (COVID being an example). Also, from that answer I checked the recorded delays at https://awt.cbp.gov and between 5 and 6 am the max delay is very short, but I really don't know what the process of entering entails, so I don't know if that short delay is sufficient time.
I am entering the US from Argentina (I'm an Argentinian citizen) with a B1/B2 visa and a return flight already purchased. I'm entering for the first time in over 20 years, last time I was there I was 10 years old, and to my knowledge I didn't overstay. Also, I don't know if I have to get my luggage and board the new plane or if the luggage is transferred between planes automatically (both tickets were purchased at the same time, both with the same airline).
Thank you for your help.
