MOST BELOVED MITZVA

Mori V'Rabi Harav Hagaon R. Shlomo Miller shlita said, "Instead of arranging the timing of הדלקת נרות so it won't interfere with your travels, you should  rather arrange the timing of your travels so it won't  interfere with the הדלקת נרות. Lighting Ner Chanukah is the only Mitzvah that the  Rambam writes (Hl. Chanukah 4:12) מצוה חביבה היא עד מאד   (most beloved Mitzvah)  The Rambam also writes והדלקת נרות - כקריאת מגילה  Perhaps the Rambam meant that  the same way קריאת מגילה is דוחה all Mitzvos even דאורייתא (except מת מצוה) so too הדלקת נרות is דוחה all Mitzvos. Being it is such a great Mitzvah one should try to avoid traveling if it will interfere with this beloved and important Mitzvah."
