Interestingly, this upcoming one is turning out to be our most complex winter ever! We have never had as many reservations and separate itineraries during a four month period.
Today, Jay and I spent some time printing out schedules that have changed since our initial bookings.
For example, recently Air Mauritius cancelled a flight from Antananarivo and put us on one the following day. We checked with them directly but the Expedia itinerary did not auto-update. So, we called to ensure our correct data showed on the website.
Even our beginning Air Canada flight to Dubai has changed. We booked a direct flight but now they've changed our itinerary so we have to change planes in Toronto! We will have to leave in the morning, but one benefit is we'll arrive about five hours earlier and no longer after midnight.
When there's just a flight or two, I'll happily download boarding passes to my phone. However, as we have over a dozen different bookings, I find printing it all on paper rather comforting.
