Heya,
I've flown FlyDubai a few times now, from DXB to DMM and from DOH to DXB. Some comments on them:
- The planes are new and pretty clean.
- They do "nickel and dime" you quite often, charging for everything. However, the charges are still very reasonable, and for a 1 hour flight you can do without IFE, Food, or Beverage.
- WRT to the carry on limitation, I generally get by pretty easy. I carry a laptop backpack, and it can run upwards of 18kg when fully loaded. Fortunately, as it is a backpack, I found that even airlines that are strict on carry ons do not bother to weigh mine.
- My flights have left ontime, staff are nice, and one of the flights was relatively empty (I had the whole row to myself).
