Rio de Janeiro
London: Aerlingus flights
I flew them (on a short Dublin-London flight), and it was alright. Nothing special to report.
Paris: Best views of Paris for dates?
The obvious answer is the Basilique du Sacre-Coeur in Montmartre, though Place du Trocadéro is nice too, with a nearby view of the Eiffel tower. Less well known is the hilly Parc des Buttes Chaumont. Enjoy :)...
