Traveling During Chemo

I'd like to hear your thoughts in regards to traveling by airplane during chemotherapy.  Did any of you take any vacations during your treatments?

My gyn/onc has encouraged me to take my trips, flying in planes.  I do plan to wear a mask on the plane, because the air is just recirculated air.  My biggest concern is the length of  my flight, because I get claustrophobic sitting too long, and my flight is about 4 hrs. long.
