You may want to consider flying Maya Air. They have been having 50% off sales pretty regularly. This would make it cheaper to fly, quicker, and less hassle. These are unavertised fares, and its pretty much hit or miss. Best thing to do is walk over and ask Maya at the airport. If no sale then take the Taxi. Its very true that if you pair up with another couple first the worst that should happen is they will charge an additional 2 or 3 BZ dollars.
