Normal airmail takes anywhere between 10 days to 3 weeks.
DHL is a good (but expensive unless u r getting discounts as mentioned earlier) alternative. Had a good experience with them recently. WHile u track the shipment on web, u can choose to be updated on ur mobile or in ur email and as the consignment reaches every hub on the way, u get a sms/mail with the status. Took a li'l over 50 hours to deliver.
Not sure how good the tracking is with Speed Post, and with Air Mail, there is no tracking i guess.
