I am trying to write to a couple of airlines from portuguese-speaking african countries, asking for their timetables. Would someone be so kind as to translate the following:

Dear Sir or Madam.

Please could you send me two copies of the Air Bissau timetable to the address above. I have enclosed some International Reply Coupons which can be exchanged at a post office to cover the cost of postage.

Thank you very much.

Yours,

Thanks!

It's probably not perfect and Brazilian Portuguese, but I'd be glad to help you:

Prezados senhores e senhoras,

por favor tenham a gentileza de enviar duas cópias do plano de vôos da Air Bissau ao endereço acima. Junto com este pedido, envio-lhes "International Reply Coupons" (cupons de resposta internacionais) que podem ser trocados em qualquer agência postal, para pagar os custos de postagem.

Muito obrigado pela sua gentileza!
