Flights £573 + hotel £200, taxes in · a checked bag each adds about £181
Frontier · with a stop · 7h 24m
The catch: The Frontier fare has one stop and takes 7h 24m out, the hotel in the total is dorm beds, and a checked bag is about $240 for two.
Worth it if you're two easygoing travelers happy with hostel beds and a stop; skip it if you want a private room or a nonstop.
