I love TripMasters!
I love TripMasters. I have used them over a dozen times for international travel and always had a great experience. On several occasions when issues have arisen, including cancelled flights, and once a railroad workers strike, TripMasters has acted early and helpfully to resolve the situation. I recommend TripMasters very often to friends. The app could get a little better functionally but the pricing and customer support is always fabulous.
