Flights £623 + hotel £366, taxes in · a checked bag each adds about £181
Frontier · with a stop · 5h 47m
The catch: Frontier connects, so the outbound takes 5h 47m against 2h nonstops, and a checked bag is about $240 for two, not in the total.
Worth it if you'd rather save on the fare than on the hours; skip it if you want a nonstop or a downtown bed.
