their tix are cheaper because they add about two more rows into the plane making them able to add more people cutting down on leg room. i'm 6'2" and had the wire from the seat back pocket digging into my kneecap the whole flight.
For International Flights Delta does not charge for the first bag... However they do charge for the first bag on Domestic Flights..... I think it is $20.00 if I remember correctly.
Turq - Yes but you must connect thru Fort Lauderdale (FLL) with one flight from ACY that goes to Orlando (MCO) then to FLL then to CUN. Same in reverse. I just flew CUN - FLL - MCO and back. My base fare was $63.00 I checked one bag each way @ $23 = $46, and an overhead carry on one way for $20. Total baggage was $66, more than the base ticket. So I am now at $129. The taxes were $118.26. Grand total $247.26. Cheaper this time than Jet Blue as I caught a $35 off deal. Normally, for me Jet Blue is less overall unless I can cram all my stuff in my backpack. Not normal is that in March I caught another deal, $50 off from CUN - DTW - LGA. Connection times are not bad but cheaper than Jet Blue on the dates I booked and I could not afford to wait as this trip was time critical. (My birthday in the Big Apple with my daughter.)
i just flew to cancun via USAir in June.. and they charged 25.00 for checked luggage.. and im flying airtran in march, and the rep said they charge 20.00 for checked luggage to CUN, which is international..
