I already skip London when using frequent flier tickets. Taxes on a JFK-LHR RT is a ridiculous $645 on a FREE ticket. JFK-CDG (Paris) is under $100. Guess where we’re going?
Gee, every time I’ve been delayed because of a mechanical problem, I’ve been thankful that the problem was found before the craft was airborne.
If there’s a mechanical issue, I want the mechanics to take however long they need to properly fix the problem, not be under pressure from beancounters to finish in time to come in under a 3-hr waiting time for passengers.
