It has been the same price since last week, which is end-Apr, for a end-Jul trip. 3 months out! Guess I've forgotten how peak "peak season" really is
This is really the highest pricing I've seen on this route for a while. I'm always looking at fares to UK during the busy July school holiday period and I'm surprised it's so sold out this far in advance.
Caught me by surprise too, given its 3 months out and how high prices are. Been talking to friends who fly to LHR regularly and they too were surprised - wonder whats going on!
