Thomas Cook Airlines has launched new set of promotional rates for departures ex Manchester to various Carribean Isles. Currently you may book cheap flights to tropical isle Barbados already from €378, you may fly to famous St. Lucia from €415 or to Antigua from €423! Real availability of these air tickets at this rate level is within Q1 of 2014, booking is possible directly with Thomas Cook Airlines here.
*UPDATE* – I have just found super cheap flights to Barbados for GBP275 (roughly €319) in travel period from 9.3. – 20.3. You may also depart on different date for similar rate but you have to return on 20th of March 2014 (but for instance you may also look for arrival flight on 28th of March or 4th of April by just adding 20GBP), booking sample is added below..
