I have a flight reservation, and I know my PNR (confirmation number, booking code, etc.). Unfortunately, it seems I cannot look up my reservation on the airline's website (they are a small airline and their website does not offer this functionality).
Is there any reputable website where I can look up my reservation, given, say, my PNR and first and last name (or other information I should have)?
With a quick internet search, I found a few sites which claim to provide this function, though I don't like the idea of entering in my PNR to random websites and hoping for the best (they could easily use this information to cancel my flight and collect $$$ from the airline for it).
I'd like to keep this question general so that answers are useful to others, but here is my specific situation. I booked a flight, got a confirmation email, with PNR, etc., and then changed my flight by emailing customer service. They emailed back telling me they had changed my flight, but didn't provide any other sort of confirmation. Obviously I can just email back and ask for a ticket/itinerary summary, but I can imagine a situation (e.g. urgent travel) where it would be extremely helpful to be able to look up a flight reservation without going through the airline that issued it (or which is operating the flight).
