My husband has MM and we had planned a European River Boat trip before he was Dx with MM. We are quite concerned about traveling in an air plane for so long as we live in California and would be flying to Amsterdam. How many MM patients have traveled abroad when your WBC were very low (between 1.6 and 3.1) ? We would be traveling in the Spring. Also, what precautions did you take besides, washing hands often, use of hand sanitizer, and avoid people with coughs. We need to pay our final payment at the end of the month and would like to hear your experiences with travel and MM. Thanks Laura
