Q. This happened in 2012. I was flying from San Diego to Bahrain with connecting flights in both Washington Dulles and London Heathrow. My departure from San Diego was delayed for more than 2 hours due to mechanical problem. Because my travel was a government order, I accepted a rerouted flight to San Francisco and then to Dulles. I was stuck in San Francisco for over 2 hours. I missed my flight from Heathrow to Bahrain and was stuck in Heathrow for over 6 hours. Can I still submit a claim for phone expenses and for the inconveniences as a result of those delays?

A. That was a long time ago, but if you have records I’m sure Delta would at least give you a travel voucher. I was on a flight from JFK to LAX on American recently and the plane had a technical problem. Then the crew “timed out” (meaning the pilots couldn’t work any longer per FAA regulations), so American gave me a $300 voucher for future travel when I asked. It does depend on your status in the frequent flier program, how long the delay was (in my case the flight was canceled around 1 a.m. and then rescheduled for 6 a.m. that morning).
