Houston to S. America, HF Radio?

Can anyone tell me if airliners typically use HF radio on this route?

It cuts close to land at the Yucatan, but not sure how the ATC is
done. VHF or HF in the remote part of the route?

Thanks
Tom

Can't say for sure but I'm an SWL and there's an awful lot of activity on
the HF frequencies from aircraft enroute over the Carribean and Gulf of
Mexico.

I've flown to Uruguay twice on United, and regularly listen to Channel
9 (cockpit communications). All VHF, as far as I can tell. (And when I
fly to Europe, they pipe HF onto Channel 9)

There is good VHF coverage over the Gulf in the flight levels. Low level
aircraft will typically relay position reports to overflying aircraft.
Nearing the Yucatan, the VHF coverage is comparable to service in the US.
The only times I used HF over the Caribbean were for sending company
messages and for setting my watch.
