I have traveled a lot, but I've never run across something this entertaining during the safety speil. This South West Airlines flight attendant should go on the road with Bob Marley!
If you aren't lucky enough to have such an entertaining attendant, here are a few tips to make your flight at least a bit more comfortable:
Choose an exit row, for an extra fee you get extra room
use an eye mask and ear plugs
bring an extra sweater or travel blanket
pack an inflatable neck pillow
bring you iPad or kindle along
Pack your toiletries
