I too checked our flight schedule. Surprise...our flight home is not affected (so far) but our flight to Belize is and this impacts us more than the other would. I don't have a problem tacking on an additional day in Belize or Houston, anything to avoid coming back to minus 20 degree temps.
Continental now has us flying to Calgary, then Calgary to Houston with an overnight and then off to Belize the next day. We weren't prepared to leave until the late evening of the 30th for Calgary and were going to overnight there and then off to Houston and Belize on Dec 1st.
Hubby is traveling in on the 29th from Venezuela and if his schedule changes we could end up waving at each other as his plane heads into Texas and mine (ours) leaves for Belize. :-(
All part of the adventure I guess.
