I believe from Nov 2018 that is only direct flight to/from POP to anywhere in Europe !!! - but check for yourself and let me know if you find others .... (not one or two weeks charter flights like Thomson though)!? (even this is really a via flight, stops by on and from SDQ)
Today I saw in the Radar a flight from Manchester to POP operated by TUI, Flight BY116
Strange … That's not on the TUI UK website any more - only Manchester and Gatwick to Punta Cana.
Maybe the flights are only for packages including hotels now, no flights only. We need a contribution from Beeza to confirm what the situation is.
Did you read the previous posts tht?
