After more than 24 hours I have confirmation that my father arrived safely.
I have not spoken to him directly nor has he been able to send me a confirmation via email or skype or a text message as one would normally do when returning home to most countries around the globe. No, not in Cuba. Cubans have to rely on word of mouth or a quick phone call to relatives at $1.39 a minute.
I will await word on how my father was treated ("handled" by the Cuban authorities) at the airport upon his return.
