Guys, Phil is 100% correct, you need to stop comparing apples and cheese...
Anywhere else and you have much larger population than Belize, do you really think all the airlines survive on tourist? Come-on... a lot of places have business travelers and the residents/citizens of those countries who have a much better per capita income than Belizeans..and as such travel more and fill the seats, Belize is better than most places.. agreed..
Try this out for size... get together with all the various resorts and hotels, choose the airlines that you feel need to drop their cost to help your situation, then approach the airline/airlines with a plan to sell package deals, if you can get together enough hotels/resorts to sell packages deals and guarantee the airlines the flights will have a marketable load factor then you win because you will fill your rooms and cover your investment. Let us say small resorts/hotels, pay 10% of their possible income per month and the larger resorts/hotels pay 20% towards covering cost to guarantee loads.Is cost really that much, lets say they need 40 seats extra to make a profit, 40 seats x 350USD = 14000 USD x 1flight (week) x 4flights (month) = 56,000 USD x 3 if you like for 3 times a week = 168,000USD that let's say 50 resort/hotels may get together and put up the collateral for their exclusive packages to their resort/hotels only, get my drift? If you were to split that up evenly that would be 3,360 USD per month for each place! and your looking at in influx of 40seats x 4 x 3 = 480 extra tourist!
approximately 10 tourist per resort/hotel, that means 10 tourist just cost you 336 USD only! So its a win-win situation! You don't need to follow this formula, but work out something that is going to benefit your guys, come together and it will happen.
Mention was made of other Caribbean islands, Grenada, Tobago etc.. A lot of the flights into these islands are indirect, in other words.. to Tobago, you fly first to Trinidad which has a population of 1.3million then on the local airlines to Tobago. BA tried a direct flight to Tobago and it did not work..
Grenada, passengers are not just going to Grenada they are also traveling to the Grenadines and St. Vincent which are another 6 islands besides Grenada, some even go to St. Lucia from there or Trinidad.. that is why you cannot compare.. the airlines are always full going to these places, they are selling a few left over seats cheap to fill the flight..
I will approach a friend I know on the tourism board in Belize and ask them what they think? Maybe the government can chip in something because at the end of the day everyone benefits.
