airline itinerary has totally changed - do I panic

[chrismartinique]

I booked online in Feb through amex travel. Everything has changed.... the flight times are similar, but my flight number, my seats etc have changed. I don't travel enough to know if this is o.k. When I check the confirmation number, we are all still "in there", so I guess its o.k.

Unfortunately, it happens all of the time. You will just have to keep checking and re-selecting your seat assignments.

I would not panic - you checked out the important items and all looks OK!

This probably happened beceause you purchased your seats so long ago. Airlines don't "finalize" their schedules until closer to flight time.
I have a trip "rearranged" by the airline - they changed the city I was flying through . . . but our departure and arrival times (and airports) stayed the same.
