I often fly PMV-BLA-MIA on 9V mostly in Business Class 4-5 times a year. Overall performance has improved a lot compared to 2012 when delays of 2-3 hrs were common. They now use ex-US Airways B-737-400 for their international routes including Miami and Panama-Tocumen. FA's are average or above depends on the crew you got on your specific flight. Food in Business Class is below average but you can eat it. Drink service is way below average only soft drinks and water offered in Business Class. On return flight MIA-BLA they give you Whisky no wine no sparkling water nothing. Check-in in PMV takes an hour or so since they fill out the passenger list for MIA manually. Transit in BLA is quite easy no long walking distances BUT broken escalators for over a year now disgusting. On your return flight you have to claim your luggage in BLA what is kind of funny since there is no luggage belt. Suitcases are thrown through a hole in the wall into bag claim hall. Seating in business class is fairly comfortable (old US domestic first class) in coach very narrow seats low pitch uncomfortable for flights 1 hr or more. No inflight entertainment. Safety briefing in both Spanish and English. Because fares are much lower than on AA or Delta it s my first choice to the US. And when originating in PMV you don t have to go through Maiquetia which is a mess and waste of time.
