It’s an observation and not a criticism of American Airlines. I recently took JetBlue on one of their late-night specials to DR and the flight was delayed, but the passenger load was largely Dominican families. On my most recent trip, I took American, I changed planes at MIA for POP and even though it was summer it seemed like lots of English-speaking USA people, maybe on business. Not as if American or JetBlue should do anything about it, just saying. If you want to brush up on your Spanish and DR culture, you take JetBlue.
